What is object-is?

The 'object-is' npm package provides a utility function for comparing two values, determining if they are the same value. This is particularly useful for edge cases in JavaScript comparisons, such as NaN, +0, and -0, where traditional equality checks (== or ===) might fail or not behave as expected.

What are object-is's main functionalities?

Exact equality comparison

This feature allows for the comparison of two values to determine if they are exactly the same, including more accurate handling of special JavaScript cases like NaN and +/-0.

const objectIs = require('object-is');
console.log(objectIs('foo', 'foo')); // true
console.log(objectIs(window, window)); // true
console.log(objectIs('foo', 'bar')); // false
console.log(objectIs(0, -0)); // false
console.log(objectIs(NaN, NaN)); // true
