I was given a text. How can I search for a particular string in that and how many times it appears using JavaScript?

Text:

This is a boy . This boy is very smart . This boy does miracles.

So if I want search for string = "boy " .

How can I do that using JavaScript?

What I did ? I tried using search function of JavaScript. Is that right to use?

Thank you so much in advance!!!

@mplungjan: This question seems not to be a duplicate of the referenced earlier question as in this question the user is also asking for the number of occurrences. To achieve this I suggest to use a recursive function: split the string after the first occurrence of boy and the search for boy in the remainder of the string again. And count how many times the function has to be called. Or you split the string using boy as separator - but take care if boy is at the start or the end of the string. And count the number of elements in the resulting array.
