Over last couple of months, I have been researching on responsive web design and Mobile first approach. Will start posting my finding over next few days. Watch this space....
Very often while reviewing the code for my team, I will come across a semicolon at the start of JavaScript function as show below ; (function () { 'use strict'; ...and I often wondered what purpose it served. Guess what. It is an insurance to make sure your script works fine when all other scripts are merged together; The leading ; in front of immediately-invoked function expressions (iffe) is there to prevent errors when appending the file during concatenation to a file containing an expression not properly terminated with a ;. So there you go. Now you know what that little semicolon is doing there in your code.
