obtain words from a string using javascript

Question

I have this formula in a javascript string:

var testString = '(var01+var02+var03)/3';

I would like to know which is the best way to obtain the following result in a array:

['var01', 'var02', 'var03']

Do you wand to extract only variable names from your string? — Alexey Gorozhanov

Use a regular expression to match word characters:

var testString = '(var01+var02+var03)/3';
var result = testString.match(/[a-z]\w*/gi);
alert(JSON.stringify(result));

The g modifier makes it return an array of all matches.
