## What is it ? 

A example of loader of [`webpack`](https://webpack.js.org/), and it's used to remove `console.log()` in code

## Core Code

```js

const parser = require('@babel/parser')

const traverse = require('@babel/traverse').default

const generator = require('@babel/generator').default

const types = require('@babel/types')

module.exports = function loader(source) {

  const { loaders, resource, request, version, webpack } = this;

  

  const ast = parser.parse(source, { sourceType: 'module' })

  traverse(ast, {

    CallExpression(path) {

      if (

        types.isMemberExpression(path.node.callee) &&

        types.isIdentifier(path.node.callee.object, { name: "console" })

      )

        path.remove()

    }

  })

  const output = generator(ast, {}, source)

  return output.code;

}

```
