Question

Please use proper ES6 JAVASCRIPT SYNTAX including using Let & const correctly

Create a function called switchLetters that takes a string and an array.

*the switchLetters function should accept two arguments , a string and an array.

*The function switches letters in the string with a "/" if they are included in the array

for example

const arr = ['x', 'a', 'h', 'l', 'd' ]
replaceLetters('hello', arr)
//output: /e//o 

please do this in javascript es6 syntax

Answer 1

function replaceLetters(str, arr){
   var result = "";
   for(i = 0;i<str.length;i++){
      if(arr.includes(str[i])){
         result += '/';
        }
      else{
         result += str[i];
        }
    }
   return result;
}

const arr = ['x', 'a', 'h', 'l', 'd' ]
replaceLetters('hello', arr)
