Sublime text editor 3, Not saving But saving

I spent around 6-7 months, trying to learn code a while ago.
Learning the basics of HTML, CSS, javascript, jQuery and a few others.
I have had a break from it for a while as it was
confusing me & other things in life came up.
Now I'm ready to start again.
I have created a simple HTML file & trying to manipulate it via Javascript.
But each time I try and save the javascript file I am getting the following error (Shown in Sublime).
[WinError 2] The system cannot find the file specified
[cmd: ['esvalidate.cmd', '--format=sublime', 'C:\Users\ManDoesNotSubmit\Desktop\Es6NorwichAds\Es6NorwichAdverts.js']]
[dir: C:\Users\ManDoesNotSubmit\Desktop\Es6NorwichAds]
[path: C:\WINDOWS;C:\WINDOWS\system32;C:\WINDOWS\System32\WindowsPowerShell\v1.0;C:\ProgramData\Oracle\Java\javapath;C:\php;C:\WINDOWS\System32\Wbem;C:\PHP]
[Finished]
It is confusing me because when I close sublime & re-open the document,
my new changes have been saved but it is still throwing this error....
I have searched forums, Youtube etc.
But all the responses I have found are regarding Python, Build systems & syntax errors.
Not the specific problem I am having.
I am running windows 10, on a cheap laptop.
I have checked the system environment variables & JS is present in both the extensions & path sections, so I cannot understand why it is throwing an error..
I am opening the file directly into sublime, from my desktop so If it could not find the file, it simply would not load the small amount of script I have written..
Any help would be appreciated.

Sounds like you're missing the sublime-jsvalidate npm package. See here
To be more precise: the error you're getting is about esvalidate.cmd not existing, not the file you're trying to save.

Grunt Uglify weird characters at last line leading to no changes

I am working since month with Grunt Watch, which is using Uglify to minify Javascript files and also generating a .map file which worked perfectly since yesterday.
When I now do grunt watch and save a Javascript file, Grunt workes like intended and runs the tasks which copy the Javascript file into the public area and generating the filename.js and filename.js.map file into the public area.
Now I am refreshing the page to look my changes, but instead of my changes, the browser seems loading the old Javascript file (Yes, I am using version like filename.js?v=....).
When I look in the source code and open the Javascript file, at the end of the file following weird characters are there:
//# sourceMappingURL=filename.js.map��������������������
I am using Chrome as my browser and PHPStorm as my IDE.
I tried to convert to UTF-8, UTF-8 without BOM, changed line Feeds to LF and CRLF, but nothing seems to be the solution.
I also displayed all invisible characters to look if there is something hidden, but there is nothing.
Inside the generated file there is the console.log('Test'); I written into, but in the same file I opened in the source code, the console.log('Test'); is not there:
Open file in any IDE: [public/js/filename.js]
... function(){l=!0,console.log("Test"),c.setTimeout(fun ...
Open file in any Browser: [/js/filename.js]
... function(){l=!0,c.setTimeout(fun ...
If I delete the 2 files in the public folder, change something in the original file and save, grunt is uglifying and copying everything and it's working! But just this one time.. the next changes leading to the same weird characters and no changes to the file in the browser again.
Like I said: The whole process I am doing worked for months! But since yesterday it's not working anymore.
I didn't installed/patched anything. This behaviour came from one to another second.
Operating System is:
Linux packer-virtualbox-iso-14225xxxxx 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1 x86_
I am searching since yesterday, but can't find any solution or idea what is wrong.

Used to have the same problem. You should turn off your sendfile in nginx.
sendfile off;
see https://github.com/mitchellh/vagrant/issues/351#issuecomment-1339640

I just restartet my computer and it seems working right now.
But if anyone has a suggestion to prevent this or solving this problem in the future, I would be happy to hear from it! If in the next few days no answer comes, I will mark my answer as solution.

Adding JQuery/Javascript Files to Project

I have a project I am working on at work that is ASP.NET in TFS. I have checked out the solution and have made some adjustments to the code behind with no issues. When I try to add JQuery and a Javascript file to the project, it does it fine in Visual Studio 2012. But when rebuilding and running it won't execute the javascript code. It's like it ignores it. When I put breakpoints in the Javascript file I get the message 'The breakpoint will not currently be hit, no symbols have been loaded for this document'. I simply cannot get the web page to acknowlegde either the JS file, or the JQuery file.
(And yes, I have scoured StackOverflow.com and tried all the suggestions mentioned)
Any suggestions appreciated!

Why do some PHP or JS files get uploaded as one-line rather than keep formatting?

I am offering zip files of a plugin I wrote with JS, PHP and CSS files for the user to upload to their server. However, in some user cases the JS file gets uploaded as one line, obviously causing a massive FAIL and a complaint from users. To get it working again, I just open the file and copy/paste from my properly formatted version onto theirs. Presto! So, can someone explain what is going wrong here and how I can prevent this easy-to-fix but time consuming problem? I am using Notepad++ on Win, is there some kind of setting I should be using to save my files? Or is it a remote server problem that I just can't prevent?

Most likely this is caused by different line endings and their interpretations on various operating systems. I would thought that nowadays these problems are over, apparently not.
Ask your customer for any file created on the target system and see what line ending is natively used there. Then simply give them file for the target platform (AFAIR Notepadd++ allows you to save file in with any EOL).

Strange characters in Javascript causing it to not load

My site works fine on localhost, my javascript is loading and working fine. But when I deploy the site the script is not working. When I right click the page and say view source and then view the linked script file, it has some strange characters at the start of the file (function($){
On localhost, my script file starts like this (function($){
What is causing these characters to be prepended to my javascript file?

You have to re-save the file in encoding "UTF-8 without BOM".
You can use Notepad++ or other editors.
In visual studio:
By default, Visual Studio uses UTF encoding with the BOM; however, you can save it to a different encoding if you'd prefer. When you go to the Save As dialog, you can expand the Save button to see the 'Save with Encoding' option. This will prompt you for a different encoding, and I think one of the Unicode options will leave out the BOM (somewhere in the list is UTF-8 without signature).

I think Briedis is right about the problem, but I suggest a different solution.
When you serve the file, is it being served with a Content-type like
Content-Type: text/javascript;charset=US-ASCII
?
If so, make sure to serve it with a charset of UTF-8 instead.

I just hit this same problem, and have found a fix.
As an answer to Martjin's question, the problem is that these URF-8 BOM characters invalidate the javascript when the client is expecting pure ASCII. So it will say there is an error at char 1, line 1 or some such, basically, right at the beginning of the file because it makes the codefile look like there's a typo in the first few bytes of the script.
In my case, I have a Site in IIS that is an ASP.NET app, and an Application underneath it that is also an ASP.NET app. This had caused some complications with inheriting web.configs, and the solution was to put a tag that negates inheritance from that point on.
I then discovered that all my .js in the child site was throwing an error for that stupid UTF-8 encoding symbol that was the first 3 bytes of every file. I am reasonably confident, that it is caused by some confusion in the httphandlers from my 2-tier solution for web.configs.
My solution, however was to convert the .js files back to pure ASCII, as that's what IIS was sending out and the client was expecting. For me, I have a build.bat that copies all the web files, removes any source control and project files and puts them all in a final build directory for copying to the test or production server. I made a modification to that script to also convert all the .js files to ASCII format.
It uses a combination of DOS batch (because that's where I started) and PowerShell (because that's the only way I found to convert without adding even more utility programs):
set DIRTOCONVERT=whatever path you want it to convert all the files for
ECHO remove UTF-8 BOM chars ï»? from front of files
for /r %DIRTOCONVERT% %%g in (*.js) do (
powershell -command "gc -en utf8 \"%%g\" | Out-File -en ascii .\tmp.txt"
move /y .\tmp.txt "%%g"
)
Note, a few people online (even in StackOverflow) had the idea to try:
type badfile.txt > goodfile.txt
but that still carries over the UTF-8 encoding. Apparently, it did not used to do that.

I had a similar issue, and found the fix when stumbling on this thread.
There was indeed a problem with the files not being UTF-8 (without BOM), but re-saving my js files as utf-8 didn't work, instead, it was my HTML file that imported these scripts that was the culprit. After I saved that file as UTF-8, the issue was resolved.
