In this lesson we'll learn shorthands for common character classes as well as their negated forms.

var str = `Afewserg, %8392 ?AWE`;

var regex = /[a-zA-Z0-9]/g;
// the same as:
var regex = /\w/g; // Find anything but not the a-zA-Z0-9
var regex = /[^a-zA-Z0-9]/g;
// the same as
var regex = /\W/g; var regex = /[0-9]/g;
// the same as:
var regex = /\d/g; // Find anything but not the 0-9
var regex = /[^0-9]/g;
// the same as
var regex = /\D/g; var regex = /\s/g; // match all the space // Find anything but not the space
var regex = /[^\s]/g;
// the same as:
var regex = /\S/g;
