When connecting multiple JavaScript files into an individual minified file, code minification decreases the number of HTTP requests to the server. Of course, a human would struggle to read it, but a machine would speed through it without a problem. It’s like taking a 529-page book and condensing it into a 324-page book.
#JS MINIFY TO NORMAL FREE#
Here, we have reduced 529 bytes to 324 bytes, gaining 205 bytes of free space and reducing the page load by almost 40%. That means it will load and render more quickly, reducing page load time and speeding up content. Now, let’s see how that same code looks once it’s been minified: function checkPalindrome(n)Ĭonst string=prompt("Enter a string: "), value=checkPalindrome(string) console.log(value) Īs you can see, the second block of code is much smaller and more compact. check if first and last string are sameĬonst string = prompt('Enter a string: ') This first block is regular, unminified JavaScript: // program to check if the string is palindrome or not Unminified vs Minified JavaScript Code Examples You may have to make some further changes to the code, too - for example, inlining functions, removing block delimiters, using implicit conditionals, or rewriting local variables. You’ve removed all the unnecessary white spaces, comments, newline characters, and everything that initially made the code legible. Once it’s been minified, it should be almost unreadable to the naked eye. To minify JavaScript code, you must parse it, compress it, and get the output. Some work goes into making code more compact while keeping it functional. However, the process isn’t instantaneous. However, the biggest concern is to minimize the code without altering the functionality.Ĭode minification is possible in all core programming technologies, including HTML, CSS, and - as we’re about to see - JavaScript. Code minification means optimizing code to save space, reduce page load times, and lower website bandwidth usage. Minification is also known as minimization. Kinsta customers can quickly minify JavaScript and CSS files through their MyKinsta dashboard. If you need to create a highly interactive website that runs in all browsers without any obstruction, then JavaScript is the most dependable option you can employ. Hence, alongside HTML and CSS, it’s a proficient choice to pick if you’re interested in web development. Notably, web browsers can understand JavaScript. For example, JavaScript offers complex elements such as scrolling video jukebox, 2D/3D videos, and interactive maps. Whereas HTML and CSS build a website’s structure, JavaScript adds complex features that bring interactivity to your website to engage the users. We also try to be at that level with our SaaS tool support. Kinsta spoiled me so bad that I demand that level of service from every provider now.
