replace array of words

Question

x.replace(/old/gi. 'new');
x.replace(/whatever/gi. 'whatevernew');
x.replace(/car/gi. 'boat');

Is there a way to combine those in one regexp statement perhaps and array of old and new words. PHP solution is also welcome.

Answer 1

You could do something like this:

var x = 'The old car is just whatever';
var arr = [{ old: /old/gi, new: 'new' },
           { old: /whatever/gi, new: 'whatevernew' },
           { old: /car/gi, new: 'boat' }];

for (var ii = 0; ii < arr.length; ii++) {
    x = x.replace(arr[ii].old, arr[ii].new);
}
