what is babel config node

Comment

Babel is a tool that helps developers write modern JavaScript code 
while ensuring that their code can also run on older systems.

JavaScript is a constantly evolving language, with new features and 
syntax being added all the time. However, not all systems support the
latest version of JavaScript, which can cause compatibility issues.

Babel allows developers to write code using the latest JavaScript 
features, and then converts that code into a version that can run on
older systems. This way, developers can take advantage of the newest
features while still ensuring that their code will work on a wide 
range of systems.
