typpy

What is typpy?

Typpy is a lightweight utility for checking JavaScript types. It provides a simple and consistent API to determine the type of a given value, making it easier to handle type checking in your code.

What are typpy's main functionalities?

Type Checking

Typpy allows you to check the type of a given value. It returns a string representing the type, such as 'number', 'string', 'object', 'array', 'null', 'undefined', or 'function'.

const typpy = require('typpy');

console.log(typpy(42)); // 'number'
console.log(typpy('Hello')); // 'string'
console.log(typpy({})); // 'object'
console.log(typpy([])); // 'array'
console.log(typpy(null)); // 'null'
console.log(typpy(undefined)); // 'undefined'
console.log(typpy(() => {})); // 'function'

Type Comparison

Typpy provides a method to compare a value against a specified type. It returns true if the value matches the type, and false otherwise.

const typpy = require('typpy');

console.log(typpy.is(42, 'number')); // true
console.log(typpy.is('Hello', 'string')); // true
console.log(typpy.is({}, 'object')); // true
console.log(typpy.is([], 'array')); // true
console.log(typpy.is(null, 'null')); // true
console.log(typpy.is(undefined, 'undefined')); // true
console.log(typpy.is(() => {}, 'function')); // true

Custom Type Checking

Typpy can also handle custom types. When you create an instance of a custom class, Typpy will return the class name as the type.

const typpy = require('typpy');

class CustomType {}
const customInstance = new CustomType();

console.log(typpy(customInstance)); // 'customtype'
console.log(typpy.is(customInstance, 'customtype')); // true

The 'typeof' package provides a simple way to get the type of a value. It is similar to Typpy but offers a more minimalistic approach. Unlike Typpy, it does not support custom type checking.

type-detect

The 'type-detect' package is another utility for type checking in JavaScript. It offers more detailed type detection compared to Typpy, including support for detecting specific object types like 'RegExp' and 'Date'.

is

The 'is' package provides a comprehensive set of type-checking functions. It is more feature-rich compared to Typpy, offering additional checks for types like 'boolean', 'error', and 'buffer'.
