Check out the number of Occurrences using JavaScript

In some scenarios we will have catch hold of number of occurrences while coding, like for example: In a sentence or paragraph I need to find out number of occurrences of a * (Star), how can we handle this using JavaScript, its simple and efficient.

Example: “DeveloperSnippets was helpful to *Developers, *Designers, *Beginners, and to *Everybody”

1
2
3

var str = "DeveloperSnippets was helpful to *Developers, *Designers, *Beginners, and to *Everybody";
var occurences = str.match(/\*/g);
document.write(occurences.length);

Output: 4

Explanation of the code:
The below line does everything, ‘/g’ here is for global, means it will check all occurrences of * in a given string globally.

1	var occurences = str.match(/\*/g);
