Everything you need to know about useState hook of React

A beginner's guide

Thread🧵👇

Hey👋

Hooks are powerful but confusing. Don't worry, I'll try to explain each hook in the easiest way in this thread series of React hooks

Let's start with useState, the most useful and simple hook in my opinion

Working with React hooks, first thing you need to do is to import the particular hook

It's quite easy👇

📌 import { useState } from "react";

useState hook takes a parameter as initial value of state and return an array having two values

- The first value is the current state
- The second value is the function that allow us to change our state

Let me show you the return value by printing it out on console👇

Now we know what useState hook return, it's time to destruct our value

const [currentState, setCurrentState] = useState(0);

🔹 currentState is the value of our state
🔹 setCurrentState is the function using which we can change our state value

WEAPONS OF MAHADEV

Sarvaripati Shiva is one of the most fearsome manifestations of Mahadev. Assigned with destroying all of the universes at the end of time, Shiva is one of the most fearsome warriors. He is the Mrityunjaya.
Here are some weapons associated with him:

TRISHULA: the 3 pointed blades denote creation, maintenance, and destruction or the 3 Kalas – Past, Present and Future. They also represent 3 Gunas – Sattva, Rajas and Tamas).
Shiva’s trishul can only be stopped by Shiva himself.
@onlyonenetra @DetheEsha

Trishul is also said to represent Ida, Pingala, and Sushumna. These are the three basic nadis – the left, the right and the central – in the pranamaya kosha, or the energy body of the human system.

PARASHU: axe with 4 cutting edges which Shiva gave to Parashurama. In his anger, Parashurama used the parashu to get rid of the all the Earth’s tyrannical kshatriya caste twenty-one times over.
@harshasherni

CHANDRAHASA SWORD: The divine sword Chandrahasa literally means ‘the laughter of the moon’. Ravana gave this sword to Indrajit on different occasions especially to fight against Devas.
GIRISH: A special sword of Shiva with unique characteristics.
