Kit-Kat array in JavaScript
We are required to write a JavaScript function that takes in a natural number, num, as the first argument and two natural numbers m and n as the second and third argument. The task of our function is to return an array that contains all natural numbers from 1 to num (including num) in increasing order.
But if any number is a multiple of m, we should replace it by 'kit' string,
if any number is a multiple of n, we should replace it by 'kat', and
if any number is a multiple of both m and n it should be replaced by string 'kitkat'
Example
The code for this will be −
const num = 50;
const m = 5, n = 6;
const kitKat = (num = 1, m = 1, n = 1) => {
const res = [];
for(let i = 1; i <= num; i++){
if(i % m === 0 && i % n === 0){
res.push('kitkat');
}else if(i % m === 0){
res.push('kit');
}else if(i % n === 0){
res.push('kat');
}else{
res.push(i);
};
};
return res;
};
console.log(kitKat(num, m, n));Output
And the output in the console will be −
[ 1, 2, 3, 4, 'kit', 'kat', 7, 8, 9, 'kit', 11, 'kat', 13, 14, 'kit', 16, 17, 'kat', 19, 'kit', 21, 22, 23, 'kat', 'kit', 26, 27, 28, 29, 'kitkat', 31, 32, 33, 34, 'kit', 'kat', 37, 38, 39, 'kit', 41, 'kat', 43, 44, 'kit', 46, 47, 'kat', 49, 'kit' ]
