Advanced tools
Package description
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: 2The function-arity package provides a simple way to get the arity of a function. It is similar to babel-helper-get-function-arity but is more lightweight and does not depend on Babel types. It is useful for simpler use cases where you don't need the full power of Babel.
Lodash's arity function is part of the larger Lodash utility library. It allows you to create a function that accepts up to a specified number of arguments, which can be useful for function manipulation. While it doesn't directly provide the arity of a function, it offers related functionality for managing function arguments.
