Convert 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

The output in the console −
