Closure Compiler

Closure Compiler is an advanced compiler of Java projects that can provide its users to optimize many aspects of JavaScript code by checking the syntax, variable references, eliminating dead code areas, and more.

This google-signed compiler can in some cases dramatically optimize JavaScript apps, making them less memory and computation heavy and thus able to run better without the need for wasted resources. Built by the Google corporation in order to help programmers all over the world to embrace the Java programming language that is today powering much of the modern cloud-based infrastructure, web services, and client-side tools.

While many compilers go with the route of translating the user's code to machine language and then trying to find the best optimizations, Closure Compiler works in a different way. Instead, it analyzes the complete available JavaScript source code in a project and simply searches for any type of error it can find. This can include everything from simple syntax errors, illegal operations, various looping errors, dangerous operations, and more. It can even completely delete dead code sections. The end result is an optimized code that is free from errors, can run without bugs, and can take more advantage of the available hardware without losing resources on parts of the app that can be safely eliminated.

The true power of the optimization comes in a form of re-writing lines in order for them to be executed faster and more reliably. Closure Compiler can do things like renaming basic symbols or parameters, removing unnecessary elements (comments), removing invalid references, checking data types, highlighting common errors, and much more.

In the end, the final result of putting a JavaScript code through Closure Compiler is a faster and more optimized app that will be smaller in size, faster to execute, more stable in real-world usage, and all of that without any effect on the code functionality. Users who want to review the optimization steps that this app has made can even read in-depth reports and learn what parameters got renamed, what formats changed, and more.

Closure Compiler is 100% FREE and can be used on both modern and some legacy versions of Windows OS (Windows 7, 8, 10, 11 both 32-bit and 64-bit).
