Function Expressions

Functions as values

Functions can be stored in variables:

const add = function(a, b) {
  return a + b
}

console.log(add(5, 3))  // 8

This is called a function expression. The function has no name of its own. The variable name is used to call it. Function expressions must be defined before you use them.
