express js input character count 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.
Example 2: js character certain count
var str = "Hello Lewes";
var ch = 'e';
var count = str.split("e").length - 1;
console.log(count);
