Replace all text before a certain point

javascript, jquery, regex

Solution

Use `/^.+M/` expression:

$(function() {
    var alphabet = "ABCDEFGHIJKLMNOPQRSTUVEXYZ";
    var replaced = alphabet.replace(/^.+M/,'');
    $('body').text(replaced);
});

The faster option is to use `indexOf` and `substring` methods:

$(function(){
    var alphabet = "ABCDEFGHIJKLMNOPQRSTUVEXYZ";
    var replaced = alphabet.substring(alphabet.indexOf("M") + 1);
    $('body').text(replaced);
});

Problem

``` $(function(){ var alphabet = "ABCDEFGHIJKLMNOPQRSTUVEXYZ"; var replaced = alphabet.replace(/(M).+$/,''); $('body').text(replaced); }); ``` How can I make this go in the opposite direction, replacing `M` and everything before it?
