Replace a portion of a string with something else

The replace() method accepts two arguments: the string to find, and the string to replace it with.

var text = 'I love Cape Cod potato chips!';

// returns "I love Lays potato chips!"
text.replace('Cape Cod', 'Lays');

By default, the replace() method replaces the first match. To replace all matches, you’ll need to pass in a regular expression with the global flag (g).

var chips = 'Cape Cod potato chips are my favorite brand of chips.';

// Only replaces the first instance of the word "chips"
chips.replace('chips', 'deep fried potato slices');

// Replaces all instances of the word "chips"
chips.replace(new RegExp('chips', 'g'), 'deep fried potato slices');
