Set Up Instructions
Click to view
- Download dependencies by running `npm install`
- Start up the app using `npm start`
Completion Instructions
Functionality to be added
The app must have the following functionalities
- Initially, the number displayed should be **0**
- When **Generate** button is clicked, a random number should be generated in the range of 0 to 100 and displayed
Implementation Files
Use these files to complete the implementation:
- `src/components/RandomNumberGenerator/index.js`
- `src/components/RandomNumberGenerator/index.css`
Quick Tips
Click to view
- You can use `Math.random()` function to get a random number (float value) in range 0 to less than 1 (`0 <= randomNumber < 1`)
```
Math.random()
```
- You can use `Math.ceil()` function to round a **number up to the next largest integer**
```js
console.log(Math.ceil(95.906698007537561)); // 96
```
- You can use the `box-shadow` CSS property to apply the box-shadow effect to containers
```
box-shadow: 0px 4px 16px 0px #bfbfbf;
```
- You can use the `cursor` CSS property to specify the mouse cursor to be displayed when pointing over an element
```
cursor: pointer;
```
- You can use the below `outline` CSS property for buttons and input elements to remove the highlighting when the elements are clicked
```
outline: none;
```

Things to Keep in Mind
- All components you implement should go in the
src/components
directory.
- Don’t change the component folder names as those are the files being imported into the tests.
- Do not remove the pre-filled code
