I'd like to run Javascript Code in Notepad++ without HTML.
I already tried to use NppExec (plugin) but it didn't work.
Is there another plugin that i can use?

Example Code:

var A = 1
var B = 2
var C = A + B

alert(C);

• @EatPeanutButter the syntax is valid in JavaScript. However it is seen as a good practice to end all your statement with semicolons. – Abhishek Gupta Commented Mar 4, 2017 at 17:05

To run JavaScript you need a runtime environment. This is generally provided by your browser.

You can use Node, to run javascript without browsers.

Some observations :

• You forgot to add ; in the end of statements.

• As JavaScript is an interpreted language, not a piled language. So, you can put your JavaScript code inside <script> & </script> tag and Run/Open it in the browser.

  <script> 
      var A = 1
      var B = 2
      var C = A + B
  
      alert(C); // 3
  </script>
  

You forgot to put ; in it

You need a runtime environment to run it but it should be provided by your browser

cscript.exe filename.js

runs JS locally on a Windows with access to things like

FileSystem = new ActiveXObject("Scripting.FileSystemObject");
WshShell = new ActiveXObject("WScript.Shell");
