MINIFY JS FILE CODE
Because browsers can execute code without needing to interpret it. Once the code is completed, minifying the files should be done to improve its performance. Developers need to use comments, formatting, and whitespace to properly debug the code and improve collaboration. With that said, how come developers don’t already write code that’s minimized? This can improve a website’s overall performance. Why Don’t Developers Create Minimized Cost At First?Īs you have already learned, minification delivers compact Javascript files. Microsoft Word, and other files, may be up to 90% smaller after compression.

Compression can increase the speed of file transfers, free up hard drive space, and reduce bandwidth costs. Compression - Data compression is the process of decreasing the number of bits needed for the code to be recognized.This results in a reduced file size and improved performance. Obfuscation is performed by altering the names of members, functions, variables. Unlike encryption, computers are still able to interpret Javascript files and execute them. 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.
