hoisting.js

test()
// when we invoke this function it breaks
// the variable test (const test) is hoisted but not what's stored in it
// function expressions aren't hoisted
testTwo()
// whereas because testTwo is a function declaration it doesn't break when we invoke it above the actual declaration 
// the whole function declaration is hoisted and we can use it anywhere in the global scope

// example of function expression 
const test = function() {
    console.log("hi")
}
const test = () => console.log("hi")

// example of function declaration
function testTwo() {
    console.log("hello")
}
