is-arguments
Advanced tools
The is-arguments npm package is designed to check if a given value is an arguments object. This can be particularly useful in functions where you need to differentiate between an array and the arguments object, or when trying to ensure compatibility across different JavaScript environments where the typeof operator might not suffice.
Check if a value is an arguments object
This feature allows you to check if a given value is an arguments object. It's particularly useful in scenarios where you need to distinguish between an array and the arguments object passed to a function.
const isArguments = require('is-arguments');
function example() {
console.log(isArguments(arguments)); // true
console.log(isArguments([1, 2, 3])); // false
}
example();Similar to is-arguments, isarray checks if a given value is an array. While is-arguments focuses on identifying arguments objects, isarray focuses on arrays. Both packages serve to identify specific data structures, making them useful in different but somewhat related scenarios.
Part of the Lodash library, lodash.isarguments provides a similar functionality to is-arguments by checking if a value is an arguments object. The main difference is that lodash.isarguments comes as part of the larger Lodash utility library, which offers a wide range of functions for different types of data manipulation and checking.
Is this an arguments object? It's a harder question than you think.
var isArguments = require('is-arguments');
var assert = require('assert');
assert.equal(isArguments({}), false);
assert.equal(isArguments([]), false);
(function () {
assert.equal(isArguments(arguments), true);
}())
If you have modified an actual arguments object by giving it a Symbol.toStringTag property, then this package will return false.
