iterate on objects keys to render a list of elements in react tsx in typescript

In order to iterate over an object's keys and render a list of elements in React JSX with TypeScript, you can follow these steps:

  1. Import React and the required dependencies:
import React from 'react';

  1. Define the object that you want to iterate over:
const myObject = {
  key1: 'value1',
  key2: 'value2',
  key3: 'value3'
};

  1. Create a functional component and define the JSX render method:
const MyComponent: React.FC = () => {
  return (
    <div>
      {/* iterate over the object's keys */}
      {Object.keys(myObject).map(key => (
        <div key={key}>{key}</div>
      ))}
    </div>
  );
};

  1. Export the component for use in other parts of your application:
export default MyComponent;

2 lines

In the example above, we use the Object.keys() method to get an array of the object's keys. We then use the map() method to iterate over this array and render a <div> element for each key. We set the key attribute to be the key itself, which helps React efficiently update the list when needed.

Remember to replace myObject with your actual object.
