Node/Javascrip babel configuration

Question

If i am using webpack loader : babel-loader, do i still need to have file .babelrc? Is this file still necessary? Why?
Ps:.babelrc is used only for transpile es6 to es5

Answer 1

According to Usage part of your link
use: {
loader: 'babel-loader',
options: {
presets: ['@babel/preset-env']
}
}
is inside webpack configuration object. So you don't need .babelrc if you are using webpack babel-loader.

Answer 2

https://babeljs.io/setup#installation
From Babel's documentation, you'll need the .babelrc configuration file.
