How to Implement Conditional Rendering in ReactJS Using if-else Logic?

Conditional Rendering in ReactJS Using if-else Statements

ReactJS utilizes JSX (JavaScript XML) to render user interfaces. However, conventional if-else statements are not supported directly within JSX due to its nature as a syntactic sugar for function calls.

To conditionally render elements, there are two recommended approaches:

  1. Ternary Operator:

    • Use a ternary operator (? :) to evaluate a condition and return different elements based on the result.
    render() {
       return (
          <View>
    Copy after login
  2. Helper Function:

    • Create a helper function that encapsulates the conditional logic.
    renderElement() {
       if (this.state.value === 'news')
          return data
       return null;
    }
    
    render() {
       return (
          <View>
    Copy after login

Remember, these methods allow conditional rendering within a React component without modifying scenes or changing the component's structure. They provide flexibility to dynamically display content based on state changes or other conditional logic.
