What would you like to do?
Knowing your framework code
// Selecting an element by its ID
// jQuery
var myElement = $('#myElement');
// Without jQuery
var myElement = document.getElementyById('myElement');
// In the jQuery source code, the logic for selecting elements is actually far more complex.
// Worth looking at if you want to challenge yourself.

// There is no faster way to become a better programmer than reading (and understanding)
// the source code of frameworks that have solved problems more complex than most programmers
// are willing to tackle on their own.
