Convert nested array to string - 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
const arr = [ 'hello', [ 'world', 'how', [ 'are', 'you', [ 'without', 'me' ] ] ] ];
Example
Let’s say the following is our nested array −
const arr = [ 'hello', [ 'world', 'how', [ 'are', 'you', [ 'without', 'me' ] ] ] ]; 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
Following is the output in the console −
helloworldhowareyouwithoutme
