Check if a function is called by tagging!

Installation

Install from npm: npm install @aarondill/is-tagged

Usage

Import the default export and call it using the entire list of arguments to the function in question, stored in an Array or ArrayLike(has a length property) object.

Example:

import isTagged from "@aarondill/is-tagged";

function tag(...args) {
	// or `isTagged(arguments)`
	if (isTagged(args)) {
		// Do stuff with tag`hello world`
		return true;
	} else {
		// Do stuff with tag("hello world")
		return false;
	}
}
tag`hello world`; // => true
tag("hello world"); //=> false

Why?

Sometimes you want to provide two ways of calling a function:

func`hello ${12}`;
func("hello 12");

In order to implement any behavior allowing this, arguments must be processed entirely differently. This library helps this by allowing detection of the method in which the function was called

Special Feature:

isTagged is a type-guard in TypeScript, allowing for better autocomplete and error management!

Note: This only works if the arguments are stored in a non-internal variable(ie, not the arguments object). In order to use the arguments object with type-guarding, store it in a variable: const args = arguments
