How can we pass props to JSX components?

  To pass props to JSX components, you can simply add attributes to the components when they are defined. Props are passed as objects, where each key-value pair represents a specific prop. Here is an example of how to pass props to a JSX component:

  jsx

  // Parent component

  import React from "react";

  import ChildComponent from "./ChildComponent";

  const ParentComponent = () => {

   const name = "John";

   const age = 25;

   return ;

  };

  export default ParentComponent;

  // Child component

  import React from "react";

  const ChildComponent = (props) => {

   return (

  
  

Name: {props.name}

  

Age: {props.age}

  

   );

  };

  export default ChildComponent;

  In this example, the `ParentComponent` is passing `name` and `age` as props to the `ChildComponent`. The props are accessed within the child component using the `props` object.

  You can then use the props within the JSX by using curly braces and accessing the prop values, as shown in the example above.

  Note that props are read-only and cannot be modified within the child component. If you need to modify the props, you should consider using the state instead.
