Power Calculator in JavaScript

To create a power calculator in JavaScript, you can use the following approach:

Step 1: Define a function that takes two arguments: `base` and `exponent`. The `base` the argument will be the number to be raised to the power, and the `exponent` the argument will be the power to which the `base` will be raised.

function powerCalculator(base, exponent) {
  // code to calculate the power
}

Step 2: Inside the function, use a for loop to iterate over the `exponent` and multiply the `base` for each iteration.

function powerCalculator(base, exponent) {
  var result = 1;
  for (var i = 0; i < exponent; i++) {
    result *= base;
  }
  // return the result
}

Step 3: Finally, use the `return` statement to return the `result` variable:

function powerCalculator(base, exponent) {
  var result = 1;
  for (var i = 0; i < exponent; i++) {
    result *= base;
  }
  return result;
}

Here is the complete code:

function powerCalculator(base, exponent) {
  var result = 1;
  for (var i = 0; i < exponent; i++) {
    result *= base;
  }
  return result;
}

var result = powerCalculator(2, 3);
console.log(result); // Output: 8

You can also use the following shortened version of the function:

const powerCalculator = (base, exponent) => {
  let result = 1;
  for (let i = 0; i < exponent; i++) result *= base;
  return result;
};

var result = powerCalculator(2, 3);
console.log(result); // Output: 8
