The nullish coalescing operator only reacts to null and undefined, contrary to the logical OR that reacts to all falsy values.

Sometimes, the nullish coalescing operator might be a better choice, especially when setting defaults. 👇🏻

I have seen some technical articles with really good content, but bad structure.

No matter how good the content is, bad structure puts people off from reading your articles!

So, here are 6 tips you can use to improve your articles straightaway! 👇

1/ Split your articles into sections

Don't write everything in one section because it makes it difficult to read. Moreover, it also confuses the reader.

See the two pictures - which article is easier to read and less confusing?

2/ The layout is important

A proper layout makes an article easier and more enjoyable to read

Make use of:
- whitespace
- bullet points
- headings
- sub-headings
- images

Once again, compare the two articles without headings and bullet points.

3/ Write for clarity

Avoid using fancy words and terminology, if not needed.

If you can simplify your article, do so. Your job is not to sound smart, but to be as clear as possible.

4/ Split your text into paragraphs

Sometimes, I see articles that have 1 or 2 enormous paragraphs.

It's incredibly tiring and difficult to read such articles.

Compare the two images - isn't it harder to read the article with those walls of text?

Why has it taken me 5 years of professional software development to properly learn testing? Why are we not more concerned with adding robust tests? Why is testing not taught in many programming courses?

I swear tests have saved my ass so many times... WRITE TESTS.

React Hooks are the functions which "hook into" React state and lifecycle features from function components. Hooks allows you to manipulate state and other React feature without writing a class. Let's talk about widely used hook

useEffect hook at a glance 🧵👇🏻

useEffect hook is the heart of React functional components

If you're familiar with class components then you might know that we have various lifecycle methods but in functional components, we don't have any lifecycle methods. Instead we have a powerful hook called useEffect

By using useEffect, you tell React that your component needs to do something after render. React will remember the function you passed (we'll refer to it as our “effect”), and call it later after performing the DOM updates

So let's start by understanding the syntax first

3/15

useEffect take two parameters, first is a function and second is an array.

The function inside the useEffect will run every single time component re-render. Consider this piece of code and check the output in next tweet

{ 4 / 15 }

As you can see in the output the function is executed every single time my component re-render

{ 5 / 15 }

A complete beginner's guide to CSS Grid layout 👇🏻

Thread🧵

Grid is used for making complex web design layouts more easily as it's not so hard to master

Using Flex you can make only 1D layout but Grid gives you full power of creating 2D layout

Let's start

{ 2 / 21 }

First things first, start with giving the display property "grid" to the container element or parent element

{ 3 / 21 }

Nothing will change after adding display: flex; in the parent container becuase we need to define the width of columns. In order to set that columns width we have gird-template-columns property

{ 4 / 21 }

Let's start with defining the width of our columns.

For example, let's say I need two columns of width 60% and 40% respectively

grid-template-columns: 60% 40%;

{ 5 / 21 }
