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;
