searching for words starting with specific letters using JavaScript RegExp

Question

I need to find all the words in a string array which start with m but not have m in the middle?

var arr = "Hello my mother! how is Ramy?";

I tried that:

var ragexp = new RegExp("sm[a-z]*|^m[a-z]*", "g");
var test = regexp.test(arr);  // test should be true if anything matched

Answer 1

i hope this will be useful for you:

m[^m]*?
