how to count occurrences of a character in a string in javascript code example
Example 1: count occurrences of character in string javascript
var temp = "This is a string.";
var count = (temp.match(/is/g) || []).length;
console.log(count);
Output: 2
Explaination : The g in the regular expression (short for global) says to search the whole string rather than just find the first occurrence. This matches 'is' twice.

function charCount(myChar, str) {

for (let i = 0; i < str.length; i++)
if (str.charAt(i) == myChar)
count++
return count;
}
