Did you know these 3 JS features?

on

JS is full of hidden features honestly. Just like all other languages, you can never master it completely. 

Here I have packed 3 features that most of us don't know.

Remember, these may not be the best way to perform a task.

Check these and Comment below how many you knew 👇


1. You can add Style to Console Logs

You can actually pass a second parameter to console log method 😃. Check the example below from MDN.

console.log("This is %cMy stylish message", "color: yellow; font-style: italic; background-color: blue;padding: 2px")


Isn't that amazing?

You can use %c multiple times as well.

Check Documentation: https://developer.mozilla.org/en-US/docs/Web/API/console#outputting_text_to_the_console


2. You don't need to define parameters for a Function

I got this from a Stackoverflow question.

function myFunc() {
    console.log(arguments[0])
}

myFunc(1) // 1

You can just use the arguments array-like object.

This may not be one of your most favourite feature but still, this is a feature many of us don't know! 😌



3. Quick Tricks to convert types

Maybe these are not the best way all time, but still useful



For example, you can quickly create a (kinda)unique id this way -

let id = +new Date

Isn't that beautiful? 👀
