# JavaScript: Multiply every digit of a number three times

## JavaScript Math: Exercise-81 with Solution

Write a JavaScript program to multiply every digit of a number three times.

**Test Data:**

(11) -> 11

(66) -> 216216

(336) -> 2727216

(444) -> 646464

(1151) -> 111251

**Sample Solution:**

**JavaScript Code:**

```
/**
* Function to multiply every digit of a number three times and concatenate the results.
* @param {number} n - The input number.
* @returns {number} - The result of multiplying every digit of the input number three times.
*/
function test(n) {
// Convert the number to a string, map each digit to its cube, and join them as a string
return +[...String(n)].map(x => x * x * x).join('');
}
// Test cases
// Assign value to n
n = 11;
// Print the value of n
console.log("n = " + n);
// Multiply every digit of the said number three times
console.log("Multiply every digit of the said number three times: " + test(n));
// Repeat the above steps for different values of n
n = 66;
console.log("n = " + n);
console.log("Multiply every digit of the said number three times: " + test(n));
n = 336;
console.log("n = " + n);
console.log("Multiply every digit of the said number three times: " + test(n));
n = 444;
console.log("n = " + n);
console.log("Multiply every digit of the said number three times: " + test(n));
n = 1151;
console.log("n = " + n);
console.log("Multiply every digit of the said number three times: " + test(n));
```

Output:

n = 11 Multiply every digit of the said number three times: 11 n = 66 Multiply every digit of the said number three times: 216216 n = 336 Multiply every digit of the said number three times: 2727216 n = 444 Multiply every digit of the said number three times: 646464 n = 1151 Multiply every digit of the said number three times: 111251
