The number 2 is stored in the variable n (let n = 2;). The command n = n*n*n is then called. This last command can be replaced by:

The command n = n * n * n can be replaced by n **= 3.

In JavaScript, the **= operator is the exponentiation assignment operator. It raises the left-hand side operand to the power of the right-hand side operand and assigns the result back to the left-hand side variable.

So, when n = n * n * n is replaced with n **= 3, it means n will be raised to the power of 3 and the result will be assigned back to n. It is equivalent to performing n = n ** 3.

Here’s an example to illustrate this:

let n = 2;
n **= 3;
console.log(n); // Output: 8

In this case, the value of n is initially 2. After executing n **= 3, n is raised to the power of 3, resulting in 8. Therefore, the output will be 8.

To summarize, the command n = n * n * n can be replaced by n **= 3 to achieve the same result.
