To compress or minify a code means removing all the irrelevant characters from your source code without changing its functionality. These characters include white spaces, comments, new line characters, semicolons etc. But why is minimization of your code necessary? Well, it reduces the size to lesser kilobytes. Hence, making the loading of your website faster and providing the user an amazing experience.
Various developers write well structured code with spaces and comments. This makes their code understandable. But, at the same time it creates extra space and hence increases the load time.
- Through the removal of white spaces and indentation
- Through the removal of extra characters from variable name
- Through the removal of new line characters
- Through the removal of unnecessary if, loops and variable decelerations
- Through optimizing your conditional statements and converting arrays into objects.
- Through the removal of comments
- Through the removal of unnecessary parentheses, semi-colons.
Before the code is of 8 lines:
//it logs the string of car with that color
//by using the information passed
console.log("Car color is "+color)
After, those 8 lines are minimized to a single line code:
This is done through the removal of white spaces, extra comments; it will make it more optimized and speed up web page loading. But sometimes a user code consists of thousands lines and minifying it isn’t an easy task. That’s why there are various libraries and online tools that provide these functionalities.
Minification has become common in website designs and development. That’s why there are various tools that help you compress your code and save your precious time. Some of these are listed below:
It’s an easy to use Google Closure Compiler that comes with various helpful optimization options. Various options are provided, whichever user wants to use according to their need. For example, if a user wants to optimize their code for whitespaces only or checking the syntax of their code. Furthermore, it also checks for any errors in the code, providing the user with best results.
Minification of code refers to the removal of things that have no use in your code. This could include extra spaces, semi colons etc. It’s a useful practice and helps in the prevention of your source code being copied. In this article we saw why minimization of your code is necessary and various tools out there for this purpose. These tools provide users with various options to optimize their code on the bases of various factors such as speed, efficiency etc.
The minimized version of your code will help in increasing the loading time of your webpage and decreasing the network traffic. Hence providing both the visitor and search engines better experience.
