Today we are going to talk about some of my favorite tips, which are super easy to implement or to follow, and that can make your JavaScript code cleaner. Also keep in mind some of the things we are going to learn today apply to JavaScript in general, though the article will focus on React.


Object destructuring

To get started we will review object destructuring, one of my favorites actually, that can help to keep the code small, clean, and elegant. This topic I love so much that I actually made a whole post about it here: Write Cleaner Code By Using JavaScript Destructuring . Destructuring allows you to break down complex structures into simpler parts. Let’s take a look at an example:

const { title } = props
console.log(title);

A common place where React developers use this technique is with props. Though some people may argue that you lose context when you split the variables, it is usually the case in React, that the context is inherited by the component itself. Let’s take a look at an example to show what I mean.

First, let’s write a simple component to show Task information on the screen:

function TaskView(props) {
    return (
        <h1>{props.task.title}</h1>
        <p>{props.task.description}</p>
        <span>{props.task.completed ? 'Completed' : 'Pending'}</span>
    )
}
