create a progress bar component in react in javascript

To create a progress bar component in React using JavaScript, you can use the built-in Progress component from React-Bootstrap. Here’s an example implementation:

index.tsx
import React from 'react';
import { Progress } from 'react-bootstrap';

const ProgressBar = ({ percent }) => {
  const now = Math.round(percent * 100);

  return <Progress now={now} label={`${now}%`} />;
};

export default ProgressBar;

11 lines

In the code above, we import React and the Progress component from react-bootstrap. We then create a functional ProgressBar component that takes in a prop called percent representing the progress percentage. Using this value, we round to the nearest integer and set now prop of the Progress component to display the progress bar. We also pass a label prop with the percentage text overlaying the bar. Finally, we export the ProgressBar component.

You can use this ProgressBar component in other React components by passing a percent prop as needed:

index.tsx
<ProgressBar percent={0.25} />

In the above implementation, the progress bar will be displayed at 25% completion.
