Javascript is inaccurate, but I need a very precise answers to a quartic equation. I want to slove it with c++, that i compiled into an exe file and will update the answers in a javascript file that I include in the HTML. I need to run the exe file that is in the same folder as the .html file on the server, and pass 5 parameters to it. It will update the javascript file, but I have no idea how to run that exe file. Can anyone help me?
----EDIT----
Thanks #Quentin webassembly worked!
You can't. That would be a severe security vulnerability, if any random web page could execute any random file on your computer.
So, web pages can't execute files on your computer.

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.

I currently have a project site ( interact.rdarellano.com ) which uses PHP forms to run Bash scripts on my webserver. I'm not happy with this PHP method because it reloads the site every time that the button is clicked.
I've read that Javascript may be able to handle this task in the background. I've never experimented with Javascript so I'm hoping to find somebody that can help me achieve this or guide me on how to set this up.
Read about JSON and AJAX. Start with Jquery which has methods to deal with this.

I have a javascript that used to upload files.
The problem is I can't get the absolute path using javascript. Is there any other client-side scripting language that can be used to get the absolute path of the file and pass it to my javascript? I don't want to used server-side scripting language like php. Is this possible?
Just to get the path is fine..
You can't get the file path in client browsers. For security concern it is restricted. You will be given only the fake path is shown with file name.
