What Is a JavaScript Minifier?
This JavaScript minifier removes comments and collapses unnecessary whitespace from JavaScript code to reduce its file size, while deliberately avoiding riskier transformations like variable renaming — it never deletes a newline that could change how automatic semicolon insertion (ASI) interprets your code, such as after a return statement.
It correctly recognizes string literals, template literals and regular expressions so that stripping comments and whitespace never corrupts code that happens to contain characters that look like a comment or division operator inside a string.

टिप्स
This Is Not a Full Minifier/Mangler
For maximum compression (variable renaming, dead-code elimination), a dedicated build-tool minifier is still worth using in production pipelines.
Keep a Commented Source Copy
Always keep the original, commented source for future maintenance.
