chained-compare is a lightweight utility for evaluating chained comparison expressions in JavaScript and TypeScript. It introduces a simple and intuitive way to write multi-condition comparisons in a readable, declarative style using tagged template literals.
With chained-compare, you can write expressions like `${x} < 10 < ${y}` and have them evaluated accurately, mimicking the behavior of mathematical comparison chains.
- Chained Comparisons: Supports operators like
<,<=,>, and>=. - Safe Evaluation: Parses and evaluates expressions without relying on
eval. - Lightweight: No dependencies and minimal overhead.
- TypeScript Support: Fully typed for enhanced development experience.
Install the package using npm or yarn:
npm install chained-compareImport the compare function and use it in your code with tagged template literals:
const { compare } = require('chained-compare');
const x = 5;
const y = 20;
if (compare`${x} < 10 < ${y}`) {
console.log("The condition holds true!");
} else {
console.log("The condition does not hold.");
}Why Use chained-compare?
- Improved Readability: Write clean and natural chained comparison expressions.
- Lightweight: Zero dependencies and 4A66 minimal performance overhead.
- TypeScript Support: Fully typed for robust development.
chained-compare is perfect for developers who value clear, maintainable code while simplifying complex comparison logic.
