React Episode 4: Rendering Conditions and Lists

Welcome to the fourth episode of React Season 1! In this episode, we will be exploring how to render conditions and lists in React applications. This is an important concept to master as it allows you to dynamically render content based on certain conditions or iterate over a list of items.

Rendering Conditions

One of the most common use cases for rendering conditions in React is to display content based on user interactions or data fetching. You can achieve this by using conditional rendering with JavaScript’s ternary operator or the && operator. For example:

“`javascript
render() {
return (

);
}
“`

Rendering Lists

Rendering lists in React is another essential skill to have. You can easily render a list of items using the map function on an array. For example:

“`javascript
render() {
return (

{this.state.items.map((item, index) => (
• {item}

))}

);
}
“`
