How do you debug through a compressed JavaScript file? [duplicate]
(4 answers)
Closed 7 years ago.
I saw an interesting js file in a website, but i cannot read it because it is minimized.
Is there any service or method to convert it to a readable file?
The minimized js file is similar to the compiled output from Google Closure Compiler.
You can use http://jsbeautifier.org
There is also a similar feature provided by UglifyJs which has an option for beautifying the code:

How can I use JavaScript source maps (.map files)?
(5 answers)
Closed 1 year ago.
I am working on an HCL Commerce project and I receive this error when I load cart page locally:
File not found: /MyWebExtSitesSAS/javascript/widgets.map
I cannot find anywhere in the web references for widgets.map. Can you describe me what is this file used for, and if I can ignore this error?
I repost the answer in the comment by #disinfor because it answered my question
You can ignore that. A map file is used for debugging purposes. When
you minify code, e.g. js, css, etc. it obviously becomes hard to read
to find any errors. The map file is used by a browser to show where in
the original, unminified code the error is coming from.

How can I read ‘native code’ JavaScript functions?

Is there any way to see the native code of javascript build-in functions in browser console so I can Know the algorithm efficiency of the function and how it actually works
Ensure you are using an open source browser (or get a job where you get access to the source code of the browser you are using)
Look through that source code of that browser
Native code is program source code that has been compiled to native machine code. The source code isn't on your system unless you get it from some other source. It certainly isn't available to JavaScript.

In my project I have got a folder with .csv files. I dont know how much - it could be 1, 0 or even 50. How can I load all of them with javascript or with some javascript plugin?
Best way of doing so would be to use the fs module of NodeJS. You can read a file by using fs.readFile() and write to a file by using fs.writeFile().

You can download "yui compressor" to compress the javascript. But I does not means that no-one can read you scripts.
Their are again tool which make your compressed javascript files again readable :(
