Question 1

What is Babel?

Answer 1

Babel is a toolchain that is mainly used to convert ECMAScript 2015+ code into a backwards compatible version of JavaScript in current and older browsers or environments. Here are the main things Babel can do for you:

• Transform syntax
• Polyfill features that are missing in your target environment (through a third-party polyfill such as core-js)
• Source code transformations (codemods)
• And more!

Question 3

What is a Webpack loader?

Answer 3

What is a webpack loader?
Loaders are transformations that are applied to the source code of a module. They allow you to pre-process files as you import or “load” them. Thus, loaders are kind of like “tasks” in other build tools and provide a powerful way to handle front-end build steps.
