A switch statement is a choice control mechanism which is used in computer programming languages to enable the value of an expression or a variable to change the control flow of program operation through search and map. “How to use a switch Case statement inside a React component” is a difficult problem that many programmers are having trouble with it. Let’s read this article to find the best answer.

How to use a switch Case statement inside a React component?

Option 1: Look at the following example

A switch case statement examines an expression provided and executes the related statements depending on whether the evaluated value satisfies a predetermined condition. In essence, it is utilized to carry out various activities depending on circumstances (cases).

Switch case statement allows a value to change execution control and adhere to a selection-control method. It serves as a replacement for lengthy clauses that compare a variable to some integral values. The switch statement offers an easy solution for allocating execution to code sections according to the value of expression value. It is also known as a multi-way branch statement. In the render component, switch case is easily usable. Let’s look at following example that will explain how it functions.

In the first example, the react switch case statement in the render function will be covered. In the second example, the react switch case statement with a component will be covered.

So let’s look at both instances.

import React from 'react';
function App() { 
  const userType = 'Admin';
  return (
    <div className="container">
        <h1>React Switch Case Condition Example - ItSolutionStuff.com</h1>
        {(() => {
           switch (userType) {
              case 'Admin':
                  return (
                    <div>You are a Admin.</div>
                  )
              case 'Manager':
                  return (
                    <div>You are a Manager.</div>
                  )
              case 'Manager':
                  return (
                    <div>You are a User.</div>
                  )
           }
        })()}
    </div>
  ); 
}
export default App;

Result

You are a Admin.

Example 2:

import React from 'react';
function App() {
 function SwitchCase(props) { 
    switch(props.value) { 
      case 'Admin': 
        return 'You are a Admin.'; 
      case 'Manager': 
        return 'You are a Manager.'; 
      default: 
        return 'You are a User'; 
    } 
  }

  return (
    <div className="container">
        <h1>React Switch Case Condition Example - ItSolutionStuff.com</h1>
        <SwitchCase value={'Admin'} />
    </div>
  ); 
}
export default App;

Result

You are a Admin.

Option 2: Activate a “Switch” component 

React becomes popular mostly due to its reusable components. You can avoid the hassle of creating complicated inline code by building a customized Switch component. Additionally, understanding the purpose of a function won’t require you to switch back and forth. The custom “Switch” component will accept a prop. Depending on its value, one of the children components positioned between the opening and closing tags of the Switch component will be rendered.

Look at the following example:

let SwitchComponent = props => { 
    const {condition, childrenElements} = props 
    return childrenElements.find(element => { 
        return element.props.value === condition 
    }) 
}

You can activate a “Switch” component and add children to the parent component with unique values. This is comparable to how various cases would be written in a switch statement. Let’s examine one instance based on the switch statement we previously wrote:

<Switch test="positive"> 
<p value={"positive"}>+</p> 
<p value={"negative"}>-</p> 
</Switch>

In this instance, the Switch component will only render the paragraph element with a positive value due to the value of the test prop.
