Js Minify tool or JavaScript minification tool can be used to minify the JS code. It uses terser, a powerful JS module that works with the latest JS features.
Why minify JS code?
When you minify JavaScript code, you remove the indentation, hence the empty spaces, comments added to your code, also, a lot of the syntax is minified by updating variable names, using shorthand syntax, etc. all this reduces the size of your JS files. And when the size of the JS file gets reduced it starts getting loading faster.
Also, by minifying your JavaScript code you make it difficult for others to understand the code, so it enhances security of the code too.
When you open any webpage in your browser, the browser makes a network call to the server of the website and downloads the HTML code along with other files required by the webpage, like the CSS file, JS file, images, etc. to display them in the browser. So if the overall size of JS file is less, it is easier to download and process it.
