Top 10 JavaScript Hack for Optimized Performance

JavaScript has been ruling the tech arena for more than two decades and helping developers simplifying complex tasks. It allows developers to implement complex task web pages in a most simplified manner. For most of the developers minified JavaScript file is the common phenomena while very few developers may be aware of Optimized JavaScript code. While meeting through many developers, I have come to know that Optimized JavaScript code is something that confuses developers, some of them might be doing it, but they are not aware of this.

What is an Optimized JavaScript Code?

When combinations of uniquely programmed logics along with small hacks utilized to enhance performance and speed is known as Optimized JavaScript code. Optimization not only optimizes performance and speed but also saves maximum development time. When you save time, you save some bucks as well.

So, I am here with some useful and fruitful hacks to help Javascript developers optimize performance, enhance speed and save time. Hope, you like the article and after going through it, you may utilize the best of Optimized JavaScript code.

1. Make JS code Leaner with Combining Javascript Modules & Minifying JS Files

Leaner code make standardized code format, which helps both developers and applications by giving more readability. That is possible when you combine the JavaScript modules and minifies the JS files. Though a minified version of the code may, sometimes, be difficult to read and understand, you will get coding leaner and optimized for sure. When you have a minified source, it helps you in many ways. For example, it can reduce the page load time, remove line breaks, additional spaces, comments, and much more. These benefits are possible as the minified source shrinks file sizes.

Optimization is also a kind of JavaScript minification, which play a very crucial role not only in removing and deleting unnecessary things such as spaces, commas, etc. but also helps developers do away with unnecessary code blocks. Here are some of the significant tools and library which help you minify the code are;

• Google Closure Compiler
• UglifyJS
• Microsoft AJAX Minifier

When you have larger JavaScript file, it affect page performance such as take time to load page and impact on speed while compressing or minifying code will resolve the issue smartly.

2. Using Scope in JavaScript is Good Step Forward

Reducing dependency on global variables and closures is yet another way to enhance performance and speed of the applications and that is possible using a JavaScript Scope named 'this'. Yes, 'thi
