If you need to declare a default parameter, do you have to declare default parameters for all the parameters? code example

Example 1: javascript default parameters

function multiply(a, b = 1) {
  return a * b;
}

Example 2: js default parameter

function greeting (name = 'stranger') {
  console.log(`Hello, ${name}!`)
}

greeting('Nick') // Output: Hello, Nick!
greeting() // Output: Hello, stranger!
