Today's npm package is jsdoc-to-markdown

Documentation is as important as solving the problem. And whats better than `jsdocs`

for JavaScript apps.

The way you can define a simple JSDoc is as follows:

```
// index.js
/**
* Function to generate the Square of a Number
*
* @param {Number} x - The number to be squared
* @return {Number} Squared value of passed Number
*/
const square = (x) => {
return Math.pow(x, 2);
};
export default square;
```

And what better than auto generating the Markdown Readme from JSDoc.

Todays package jsdoc-to-markdown will allow you to do so.

All you have to do is to add jsdoc-to-markdown as a dependency and then you can run it via npm scripts

Install as:

```
npm i -D jsdoc-to-markdown
```

Add to scripts. in `package.json`

```
{
...
"scripts": {
"gen-docs": "jsdoc2md index.js > API.md"
}
}
```

And then executing the command on CLI as:

```
npm run gen-docs
```

will give us following `API.md`

file:

```
<a name="square"></a>
## square(x) โ <code>Number</code>
Function to generate the Square of a Number
**Kind**: global function
**Returns**: <code>Number</code> - Squared value of passed Number
| Param | Type | Description |
| --- | --- | --- |
| x | <code>Number</code> | The number to be squared |
```

Stay tuned for tomorrow's package of the Day.
