Hi, I see in the bootstrap.js file, the following type of pattern for all the functions ....
+function ($) {
  'use strict';
Can someone let me know what the following mean?
1) The '+' sign. I read on StackOverflow that it's to load the function immediately but why would we want to load all the functions immediately?
2) The '$' being passed into the function.
3) The 'use strict' statement.
4) The final (jQuery) bit at the end.
