babel-helper-get-function-arity
Advanced tools
The babel-helper-get-function-arity package is a utility that helps determine the arity (number of parameters) of a given function. This can be particularly useful in scenarios where you need to introspect functions for metaprogramming or code transformation purposes.
Get Function Arity
This feature allows you to get the number of parameters of a function. In the code sample, a function declaration with two parameters ('a' and 'b') is created using Babel types, and the arity of the function is determined using the getFunctionArity utility.
const getFunctionArity = require('babel-helper-get-function-arity');
const t = require('@babel/types');
const func = t.functionDeclaration(
t.identifier('myFunction'),
[t.identifier('a'), t.identifier('b')],
t.blockStatement([])
);
console.log(getFunctionArity(func)); // Output: 2TODO
