Converting multi-dimensional array to string in JavaScript

We are required to write a JavaScript function that takes in a nested array of literals and converts it to a string by concatenating all the values present in it to the string. Moreover, we should append a whitespace at the end of each string element while constructing the new string.

Let’s write the code for this function −

Example

The code for this will be −

const arr = [
   'this', [
      'is', 'an', [
         'example', 'of', [
            'nested', 'array'
         ]
      ]
   ]
];
const arrayToString = (arr) => {
   let str = '';
   for(let i = 0; i < arr.length; i++){
      if(Array.isArray(arr[i])){
         str += `${arrayToString(arr[i])} `;
      }else{
         str += `${arr[i]} `;
      };
   };
   return str;
};
console.log(arrayToString(arr));

Output
