How to count how many repetitions a particular character has

var temp = "This is a string.";
alert(temp.count("is")); // output '2'

I'm looking for a function that counts how many strings in a particular string into a parameter when I insert a string like this, but is there a function like that in JavaScript?

You can do it simply by writing a regular expression.

var temp = "This is a string.";

var count = (temp.match(/is/g) || []).length;

alert(count);
