A simple JavaScript utility that returns true if a given number is even.
is-even is a JavaScript utility library that checks whether a given number is even. It solves the basic problem of determining number parity in code, providing a simple, reusable function that works with both numeric and string inputs.
JavaScript developers who need a straightforward, dependency-free way to check if numbers are even in their applications.
Developers choose is-even for its simplicity, reliability, and zero dependencies, making it an easy drop-in solution for a common programming task without adding bloat.
I created this in 2014, when I was learning how to program.

The library has no dependencies, making it lightweight and easy to integrate without adding bloat, as emphasized in the README's description.
Handles string inputs by automatically coercing them to numbers, as shown in the usage examples with '1' and '3'.
Accurately identifies zero as an even number, which is mathematically sound and mentioned in the key features.
Does one thing well without unnecessary complexity, aligning with its philosophy of providing a reliable, simple function.
The functionality (`num % 2 === 0`) is so basic that adding a library can seem like overkill compared to inline code.
Only checks for even numbers; for odd checks, developers must use negation or additional logic, lacking a built-in solution.
The README is generated by a tool, which might result in less personalized documentation or detailed examples for edge cases.
