String match angularjs/javascript max 2 characters

Question

i've got a function that matches all letters after a space. I mean;

"this is my string" --> tims

just doing this:

$scope.getLetters = function(str) {
            var matches = str.match(/\b(\w)/g);
            var acronym = matches.join('');
            return acronym;
        }

where str of course is the string that i pass from the html. It works pretty well but i would extract max 2 characters. So if the string is

"this is my string"

i would ti only and not the others. How can i do it?

Use slice before join:

var str = "this is my string";
str.match(/\b\w/g).slice(0,2).join('')
//=> "ti"
