js count how many a charcter is in string 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: how to check how many strings are in a sentence javascript
function WordCounter (str) {
var words = str.split(" ").length;
return words;
}
