How to Implement Conditional Rendering in ReactJS Without Using if-else Statements?

Conditional Rendering in ReactJS: if-else Statements in JSX

In ReactJS, the if-else statements cannot directly be used within JSX expressions. This is due to the nature of JSX, which is a syntactic sugar for creating JavaScript function calls and objects.

To conditionally render elements based on state, there are alternative approaches:

Ternary Operator:

Use the ternary operator to evaluate a condition and render different elements based on the outcome, as shown below:

render() {
    return (   
        <View>

Function Invocation:

Create a function that evaluates the if-else logic and returns the appropriate element. Then, call the function from within the JSX expression:

renderElement(){
   if(this.state.value == 'news')
      return data;
   return null;
}

render() {
    return (   
        <View>

By utilizing either the ternary operator or function invocation, you can conditionally render elements in ReactJS without modifying the scene or using tabs.
