use proper ES6 syntax including using let/const properly, code this in javascript !

Create a function named trackingStrings , it counts the number of times those words are present in the array

The trackingStrings function accepts an array argument. The solution will be an object with the key as the string and the count as the value.

const arr = ['happy', 'john', 'jones', 'john', 'jones', 'happy' , 'sad'] countingWords(arr); //output should be { jones: 2, john: 2, happy: 2, sad: 1 }

please write this in javascript es6 syntax using "let" and "const" , no html
