PHP's strcmp in TypeScript

How to use

Install via yarn add locutus and import: import { strcmp } from 'locutus/php/strings/strcmp'.

Or with CommonJS: const { strcmp } = require('locutus/php/strings/strcmp')

Use a bundler that supports tree-shaking so you only ship the functions you actually use. Vite, webpack, Rollup, and Parcel all handle this. For server-side use this is less of a concern.

Examples

These examples are extracted from test cases that automatically verify our functions against their native counterparts.

#	code	expected result
1	strcmp( 'waldo', 'owald' )	1
2	strcmp( 'owald', 'waldo' )	-1

Here's what our current TypeScript equivalent to PHP's strcmp looks like.
