The @babel/plugin-transform-exponentiation-operator package is a plugin for Babel, a JavaScript compiler, that allows developers to use the exponentiation operator (**) in their JavaScript code. This operator is used to raise the first operand to the power of the second operand. The plugin transforms this syntax into a format that is compatible with environments that do not support the exponentiation operator natively.

What are @babel/plugin-transform-exponentiation-operator's main functionalities?

Exponentiation Operator Transformation

This feature allows developers to write code using the exponentiation operator (**) for performing exponentiation operations. The plugin then transforms this syntax into a call to Math.pow, ensuring compatibility with older JavaScript environments.

"use strict";\n\nvar _Mathpow = Math.pow;\n\nvar a = 2;\nvar b = 3;\nvar c = _Mathpow(a, b); // Transforms a ** b into Math.pow(a, b)
