Here are some basic stuff from JavaScript. Even if you write the most advanced JavaScript code it's worth to sometimes refresh memory about basic stuff.

I'm challenging you to write in the comments what did you forget from this list?

<!DOCTYPE html>
<html>
    <head></head>
    <body>
        <script>

// console.log("Hello, Vue! 馃帀")

// this is a single-line comment

/*
  this is a multiline comment
*/

// this is a multiple single-line comments
// this is a multiple single-line comments
// this is a multiple single-line comments

"use strict"

var bin = true
var str = "hello, world!"
var num = 3.14

console.log(bin)
console.log(str)
console.log(num)

var arr = [
    "hello, world!",
    "hello, darkness..."
]

console.log(arr)
console.log(arr[0])
console.log(arr[1])

var obj1 = {
    key1: "val1", // or "key1"
    key2: "val2"
}

console.log(obj1)
console.log(obj1.key1)
console.log(obj1.key2)
console.log(obj1["key1"])
console.log(obj1["key2"])

var obj2 = {
    obj3: {
        key1: "val1",
        key2: "val2"
    },
}

console.log(obj2)
console.log(obj2.obj3)
console.log(obj2.obj3.key1)
console.log(obj2.obj3.key2)
console.log(obj2.obj3["key1"])
console.log(obj2.obj3["key2"])

if (false) {
    console.log("if")
} else if (false) {
    console.log("else if")
} else {
    console.log("else")
}

false ? console.log(true) : console.log(false)

for (var x = 0; x < 3; x++) {
    console.log(x)
}

for (var msg of ["how", "are", "you"]) {
    console.log(msg)
}

function fun(arg) {
    if (!arg) {
        arg = "world"
    }
    return "hello, " + arg + "!"
}

console.log(fun)
// console.log(fun())
// console.log(fun("js"))

        </script>
    </body>
