After the recent Eclipse update (Version 4.17.0, Build 20200910-1200) the syntax highlighting for Javascript files is not working any longer. Furthermore the *.js file association and the Textmate section are missing in the preferences.
Does anybody experience similar problems?

after updating my Eclipse IDE to the actual 2020-06 version the syntax highlighting for JavaScript does not work any more.
Is this a known/common problem and how can I fix this?
After spending most of a day futzing with it, including installing a new instance of Eclipse PDT, I found that I could fix it simply by adding *.js to the File Associations preference page and setting its default to "Generic Text Editor".
Per the Eclipse Bugzilla Report:
Standalone JS Editor is not provided anymore.
To work with JavaScript/TypeScript projects users may install JS [1] or JEE [2] EPP packages, WildWebDeveloper [3] or other products.
[1] https://www.eclipse.org/downloads/packages/release/2020-06/r/eclipse-ide-web-and-javascript-developers
[2] https://www.eclipse.org/downloads/packages/release/2020-06/r/eclipse-ide-enterprise-java-developers
[3] https://marketplace.eclipse.org/content/eclipse-wild-web-developer-html-css-javascript-typescript-nodejs-angular-json-yaml
Basically this means that the Eclipse JavaScript Development Tools (JSDT) is no longer supported.
It could just be me, but [1] seems to be a pretty stripped-down version of Eclipse. It doesn't even include Package Explorer, which baffles me. [2] is a bit better in my opinion, at least having Package Explorer. (I do love Package Explorer 😜) However, I'm not really interested in installing a new version of Eclipse when the way [1] and [2] implement JavaScript support is through [3] Wild Web Developer ("WWD") anyway. (You don't have to follow that link for [3]; you can find it in the Eclipse Marketplace just fine. Also, you'll have to reopen any JavaScript files you have open for the update to work.)
I added WWD through the Eclipse Marketplace on my Windows x64 version of Eclipse IDE for Java Developers, 2020-06. I guess it works, but it sure doesn't integrate like JSDT did.
I'm not thrilled with WWD since the first thing I tried to do is comment a line in JavaScript using Ctrl+/ and it summons a dropdown of keyword and available function choices. Ctrl+. does the same thing, and feels more appropriate, so what's the deal? 🤨 Want to change the keyboard shortcuts? Too bad. There's nothing under the Keys preference that has anything to do with TextMate/WWD actions.
Want to change the syntax coloring? Better love what you're given. There is no Syntax Coloring section or anything like it. There's a TextMate set of preferences, but it seems like anything regarding Theme doesn't actually work. Is it because I use DevStyle and the Darkest Dark theme? Who knows.
There's only one WWD preference (XML), which does nothing but tell you "See 'XML Catalogs' for XML catalogs preferences". Thanks? It's also version 0.10.0.etc, which feels like we're being forced to test it. Overall I'm pretty disappointed, especially since Eclipse just automatically upgraded itself from 2020-03 to 2020-06 and now I'm stuck with this. Boo to you on this move, Eclipse 😞
This is how I fixed it:
Install "Eclipse web developer tools 3.20" from Eclipse marketplace
Restart
Open a JS file. Right-click on line number > Switch to theme > Eclipse light.
Done.
I am currently trying to code on Eclipse using JavaScript, but I am having a lot of troubles when tying to add JavaScript to Eclipse. I followed the instructions on this website (JavaScript Editor Plugin for Eclipse), and everything was going well until step 9 of the first part. JavaScript Viewer is not one of the offered options in Editor Selection. I am very confused as to what to do. Any help would be appreciated!
Thank you in advance :)
Version: Eclipse Oxygen on MacOS. Oxygen.3a Release (4.7.3a)
You could give the latest Eclipse IDE for JavaScript and Web Developers bundle a try.
It provides:
The essential tools for any JavaScript developer, including JavaScript, HTML, CSS, XML languages support, Git client, and Mylyn.
With this recent (2018) version of Eclipse, you should get a working JS-enabled IDE pretty fast as this is pre-bundled for the use-cases you are looking for:
JavaScript Development Tools
Eclipse XML Editors and Tools
[..]
Hope it helps.
FYI -- I ran into this problem with the latest version of eclipse [2020-06(4.16.0)]. It turns out they removed the Javascript editor from the install. See ref here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=564496
Bottom Line Up Front: Eclipse Neon content assist (Ctrl+space) does not offer any proposals for my JavaScript code.
Here is what I've checked so far:
JSDT has been installed
"JavaScript resources" include ECMASciptBuilt-In Library, ECMA 3 Browser Support Library, jQuery
The project's Include path has ECMAScipt Built-In Library, ECMA 3 Browser Support Library, jQuery, and JavaScript Web Project support
Eclipse's JavaScript Content Assist is enabled and includes Basic proposals, Other JavaScript Proposals, Template Proposals, and word proposals.
I changed the content assist from ctrl+space to ctrl+0 to check whether ctrl+space had been hijacked
Content assist DOES work with regular Java (in a different project)
I tried reset to defaults under Content Assist > Advanced
JavaScript facet is selected for the project
.js files and .jsp files are stored in folders that are under folders that are designated as source folders in the project properties under JavaScript > Include Path
This is also an issue in Mars 2.
I've run through the steps listed here for configuring content assist: http://www.eclipse.org/pdt/help/html/using_javascript_content_assist.htm
The content assist isn't even proposing functions that are defined within the same .js file. How can I get Eclipse's content assist to propose elements correctly?
I have the same problem and it seems to be a known bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=504057
+1 not working in Eclipse Neon. As an alternative you may try Netbeans 8. Javascript is working good there. I don't know what happened to Eclipse but php and Js support is poor.
P.S. Just downloaded Eclipse Mars - can confirm that it's working fine.
I've met this situation before,and then I found that if the js file is in a "normal java project",then it won't come uip with content assist,but if the js file is in a "dynamic web project",then the content assist just work well,hope it will help.
I'm using IntelliJ IDEA 12 Community Edition, and am trying to set the syntax coloring for Javascript files. When I choose File > Settings > IDE Settings > Editor > Colors & Fonts, Javascript is not an option in the list. Is this a limitation of the Community Edition IDE, or am I missing something? The others I need are listed, like Java and HTML, but Javascript is missing from the list.
Thanks.
JavaScript support is supported in Ultimate Edition, but not in Community Edition.
For the basic syntax highlighting you can try the TextMate Bundles Support plug-in. See this document for the setup instructions (it's for PhpStorm, but instructions for IntelliJ IDEA would be the same).
The TextMate Bundles Support plug-in is not enough. You also need specific language bundles.
install and enabled the TextMate bundle support plugin in IntelliJ
Download the specific language bundles and unzip them somewhere where you find them, e.g., TypeScript, Shell Script TextMate Bundle
Open the Settings/Preferences dialog, got to Editor and select TextMate Bundles
Click on the + on the right side and choose the desired bundle from 2. on your hard disk. Then it should appear in the list of recognized bundles.
Extension conflicts might appear: Click on "Show details". If you want to use the new syntax highlighting click on "unregister native file type".
A detailed explanation with screenshots can be found here
I found this question after searching by "how to enable JS syntax highlight into JSP files" in my Intellij Community Edition.
Following the suggestion to use TextMate Bundles, I checked that it's already installed by default, including JSP support (built-in). But it did not work.
So, I fixed it by just removing the "*.jsp" pattern from "File Types > JSP", and after that now my IDE is using TextMate syntax highlight properly.
Use Visual Studio Code for Javascript support when using IntelliJ Community Edition. It's free and has all the support you would get for the paid version of IntelliJ Ultimate.
Or buy it for $149 (personal ultimate edition). I've been buying it since 2013 and find it far superior to XCode. This is just my personal opinion though. Download a trial and see how you like it!

Alternative I tried (but raised another issue):
Marked VS Code as default app to open .js files.
For IntelliJ, follow this: to configure .js files should be opened using VS Code
This has enabled to opening .js files into VS code when we command from IntelliJ Idea, but strangely, .js got disappeared from "Find in files" search list.
Inputs are welcomed, whether I had configured it wrong.
I've just setup Eclipse with Aptana Studio 3 and have been trying to get code completion / code hinting / autocomplete to work with mixed results.
I've followed the instructions here: http://wiki.appcelerator.org/display/tis/JavaScript+Library+Support
What I have discovered through testing is that when you install the .sdocml file and nothing else in a new project, it works fine.
As soon as I add a local copy of Dojo into the project the code hinting no longer works correctly.
I tried excluding the directory from view with a filter but that excludes it from the server so you can't use it. I've also tried removing the Dojo folder from Indexing but that changes nothing either.
If I load Dojo from a CDN, like Google, then I can use code completion.
The issue is that Eclipse picks up a parsed reference to dojo instead of the one from the sdocml file.
The problem seems, so far, to be confined to typing 'dojo.' but 'dijit.' and 'dojox.' work okay, maybe because of the parent-child relationship between those sub-libraries, if I were to guess.
I don't know if this is an Aptana bug or an Eclipse bug, but either way, it's a problem.
Does anyone know how to prioritize the code hinting sources and / or exclude certain directories from being a hinting source? Or is there another solution?
Thanks in advance,
Ken
Edit: Now that I have more code in the test project hinting does not work at all for 'dojo.' but still works fine for 'dojox.' and 'dijit.'. Only native JS methods hinting is available as a subset of 'dojo.'
