How to validate Regex

Question

I mean to say: for example i have a string ("this is my String")
and now i want to do this find the word from the string which contains a capital letter
So how can i do it

Answer 1

Use String.match(regex);
To search for a word, use: /\w+/g
And, for a word starting with a capital letter, use: /[A-Z]\w+/g

So, your required regex would be: "this is my String".match(/[A-Z]\w+/g);
