We’ll finally learn about some coding stuff today. It’s basic today.

We’ll writing JavaScript code on the console of google chrome. You can find it on

menu >> developer tools >> select console from the tab

shortcut: Ctrl + Shift + I

You can try Mozilla Firefox console too. It’s up to you what you want to use, but I prefer chrome, so I’m going to stuck with it. With time, we’ll go to some text-editor to write code, now we can write code in console.

Javascript have 7 types. You can think types as values. They are –

a. Number
b. String
c. Boolean
d. Undefined
e. Null
f. Symbol (new in ES6)
g. Object

Today we’ll talk about Number.

We can do all the arithmetic things here using JavaScript. Plus, Minus, Division, Multiplication etc. Easy math right ? This is all numbers, they are allowed in JavaScript.

Working on some more arithmetic logics.

Now I’ve question. Do you know what ‘%’ means in real life? I am sure you know. But check this –

It is not the same right? Think more about it.
