Return the Sum of Two Numbers in JavaScript

To return the sum of two numbers in JavaScript, you can use the following approach:

Step 1: First, define a function that takes two arguments, `a` and `b`. These arguments will be the numbers that you want to add together.

function add(a, b) {
  // code to add a and b and return the result
}

Step 2: Inside the function, use the `+` operator to add `a` and `b` and assign the result to a variable `sum`.

function add(a, b) {
  var sum = a + b;
  // return the sum
}

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

function add(a, b) {
  var sum = a + b;
  return sum;
}

Here is the complete code:

function add(a, b) {
  var sum = a + b;
  return sum;
}

var result = add(2, 3);
console.log(result); // Output: 5

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

function add(a, b) {
  return a + b;
}

var result = add(2, 3);
console.log(result); // Output: 5
