What is @babel/helper-get-function-arity?
The @babel/helper-get-function-arity package is a utility within the Babel compiler ecosystem. It is designed to help retrieve the arity (the number of arguments) of a function. This can be particularly useful when working with transformations and manipulations of JavaScript code, where understanding the function signature is necessary for generating or modifying code accurately.
Get function arity
This feature allows developers to easily determine the number of parameters that a function expects. It is particularly useful in scenarios where code is being dynamically generated or modified, and the arity of functions needs to be preserved or analyzed.
const getFunctionArity = require('@babel/helper-get-function-arity');
function myFunction(a, b, c) {}
const arity = getFunctionArity(myFunction);
console.log(arity); // Outputs: 3
