Through obfuscation, reverse engineering becomes nearly impossible. In essence, the source code is altered in a way that becomes illegible to other humans. Obfuscation - This process is done to hide secretive development practices.Therefore, this method is more of a security feature than a minimization tactic. This creates secretive data called ciphertext, which requires a special key to gain authorized access to decrypt the data. Encryption - Encryption is the process of translating plain data into encoded data.Nonetheless, uglification may enhance performance but it will unfortunately reduce readability for other collaborators. Essentially, to “uglify” a JavaScript file is to minimize it using this library. In fact, Uglify is a type of Javascript library which helps developers minimize files. Uglification - This is basically the same as minification.Minification differs from all of these, mainly because: These are obfuscation, compression, encryption, and uglification. How is Minification Different from Other Tactics?Įxperienced developers are aware that there are other refinement techniques to improve the efficiency of Javascript source code. Overall, minification can lead to faster webpage loading times, which can improve your website experience, making both search engines and visitors content. These changes may seem minute, but they can significantly impact the efficiency of your Javascript source code. Lines 4,5, and 8 have been consolidated for refinement.Line 7 has been removed because it contains no characters.The character ( }) on line 6 has been removed.The comments on line 1-3 are unnecessary and have been removed for refinement.Here are all of the changes that have been made: It’s presently only eight lines of source code:Īfter the source code has been minimized, here is what it now looks like:Īs you can see, the code now has one line. To help you understand the concept, below is a block of code before minification. By removing extraneous semicolons, comments, whitespace, along with using shorter variable functions and names, developers can create a more compact file size. Think of minification as refining Javascript code. It involves truncating all unnecessary characters of Javascript source code without impacting its usefulness and functionality. Minification, also known as minimization, is a very simple website development concept.

The method replaces symbol names with non-meaningful ones. Using this website you can also obfuscate js or JavaScript code. Obfuscation will just slow them down a bit. But, if someone is determined enough they can and will reverse engineer any obfuscated JavaScript code so that they can see the original source code. The goal is to make it so that other developers can not reverse engineer that source code and use it for their own projects. This JavaScript Obfuscator helps you to protect your JS code against theft and makes the code hard to understand. This website must help you to minify your code properly. So, we can say that minification is performed on JS source code because it is basically a performance enhancement – and it allows websites that use minified JS to load faster. What are the benefits of Javascript minification? The sole benefit of minified JS code is allowing a client to download fewer bytes, enabling the page to load faster etc. If you use the Minify JS option this will reduce file size (up to 20% smaller) which speed up script execution times and resulting in a faster loading time. This toll will not only compress js code but also remove all unnecessary comments, extra whitespace,new line characters to give you perfect output. But you can able partially reverse the obfuscation mechanism using some other tools. So a good JavaScript Obfuscator is able to minify, compress, and optimize your js code perfectly. Obfuscate JavaScript - This is a process that protect the code from the reuse of other developer. JS Optimize process will make the code run faster. JavaScript Compress - this process using non destructive compression of code. But which one is the best? You will get four kinds of mechanism such as - JavaScript Minify which make the JS code smaller by removing unneeded space, comments, renaming variables and so on. Minify, compress and obfuscate JS are now very familiar words.
