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.javascript string lentrh
var myString = "string test";
var stringLength = myString.length;
console.log(stringLength); // Will return 11 because myString
// is 11 characters long...javascript length
var colors = ["Red", "Orange", "Blue", "Green"];
var colorsLength=colors.length;//4 is colors array length
var str = "bug";
var strLength=str.length;//3 is the number of characters in bugcount value a to b character javascript
let counter = str => {
return str.split('').reduce((total, letter) => {
total[letter] ? total[letter]++ : total[letter] = 1;
return total;
}, {});
};
counter("aabsssd"); // => { a: 2, b: 1, s: 3, d: 1 }Copyright © 2021 Codeinu
