1. Default function parameters in vanilla JavaScript
  
  Today, we’re going to look at how you can set default values for function parameters when none are provided. Let’s dig in! The danger of missing parameters Let’s imagine you have an add() function that adds two numbers together. /** * Add two numbers together * @param {Number} num1 The first number * @param {Number} num2 The second number * @return {Number} The sum of both numbers */ function add (num1, num2) { return num1 + num2; } If you don’t pass in a value for a function parameter, the parameter has a value of undefined.
