Introduction

This project provides simple guard methods for throwing appropriate type errors when arguments are incorrect.

Variants supported...

• throwIf() - Throws if the parameter is null or undefined.
• throwIfNotIn() - Throws if the required parameter is not in the range of expected values.
• throwIfNull() - Throws if the required parameter is null.
• throwIfUndefined() - Throws if the parameter is undefined.
• throwIfNaN() - Throws if the specified parameter is not a number.

Sample usage

const guard = require("arg-guard");

const myFunc = function(requiredArg, otherArg) {
    guard.throwIf(requiredArg, "requiredArg");
}
