How to convert nested array to string in JavaScript

Answer 1

const nestedArrayToString = (arr) => {
    let str = '';
    
    for (let i = 0; i < arr.length; i++) {
        if (Array.isArray(arr[i])) {
            str += nestedArrayToString(arr[i]);
        } else {
            str += arr[i] + " ";
    	    }
    }
    
    return str;
};

const arr = [
    'javascript', [
        'programming', 'language', 'for', [
            '98%', [
                'of', 'websites'
            ]
        ]
    ]
];

console.log(nestedArrayToString(arr));
