Mastering the useRef Hook in React: A Quick and Informative Guide

React useRef Hook is a powerful tool for managing and interacting with DOM elements and persisting mutable values across renders. Unlike state, updating a useRef value doesn’t trigger a re-render, making it ideal for situations where you need to maintain values without causing unnecessary updates to your component.

What is useRef?

The useRef Hook creates a reference to a value or a DOM element. The reference persists across renders but doesn't cause the component to re-render when updated. It is typically used for two main purposes:

Accessing DOM Elements:You can directly interact with a DOM element without causing a re-render.

Persisting Mutable Values:Use it to store values that need to persist between renders but shouldn't trigger a re-render.

Use Case 1: Accessing DOM Elements

One common use of useRef is to interact with DOM elements. For example, you can create a ref for an input field and then programmatically focus it. When the button is clicked, the input field gains focus, all without causing a re-render.

Use Case 2: Persisting Values Across Renders

You can also use useRef to store values that need to persist across renders without triggering re-renders, such as keeping track of previous values or timers. The timer reference is maintained across renders without causing a re-render every time the timer updates.

When to Use useRef vs. useState?

useState: Use when you need to trigger a re-render on state changes. 

useRef: Use when you want to persist values across renders without triggering re-renders, especially for DOM interactions.

A Closer Look at JavaScript Boolean Variables

Learn how to work with JavaScript Boolean variables to handle true or false values. Understand their use in conditional statements and improve your coding efficiency with practical examples.

[hananina86]

First, let's declare a function,

inside a function{}, you can use "return" to get the resulting value of your code. When you call the function, it returns the value.

var quarter = function(number){ return number/4; };

Next, write an if-statement with a condition( x % 3 = 0). The number x will be a number divisible by 3. you can even call your function inside of an if-statement's condition! I passed 24 as the parameter, so it got divided by 4, in the end the function returned 6 as the value. According to the if-condition, 6 % 3 = 0, so it calls "the statement is true" yay:)!

if (quarter(24) % 3 === 0 ) { console.log("The statement is true"); } else { console.log("The statement is false"); }
