Minimized vs. Full jQuery Versions

jQuery provides two different versions to use in web pages. They are called minified version and full version. Technically, there is no difference in functionality however the file size is different.


The jQuery full version contains the code that can be easily readable by the users. The code can be readable and debugging is very easy. It is always a good not use this version because the file size would be more and loading the libraries becomes very difficult in terms of performance


The jQuery minified version contains the code that can not be easily readable by the users. Debugging this minified code is technically hard. But the goodnews about this version is, the file size is very tiny. It makes the performance very smooth.
