Usage

String Utilities

import { upperFirst, toCamelCase, toKebabCase, truncate, slugify } from "@trdev20/js-utils";

upperFirst("hello"); // => 'Hello'
toCamelCase("hello-world"); // => 'helloWorld'
toKebabCase("helloWorld"); // => 'hello-world'
truncate("hello world", 5); // => 'hello...'
slugify("Hello World!"); // => 'hello-world'

Array Utilities

import { uniqueArr, chunkArr, intersection, difference } from "@trdev20/js-utils";

uniqueArr([1, 2, 2, 3]); // => [1, 2, 3]
chunkArr([1, 2, 3, 4, 5], 2); // => [[1, 2], [3, 4], [5]]
intersection([1, 2, 3], [2, 3, 4]); // => [2, 3]
difference([1, 2, 3], [2, 3, 4]); // => [1]

Object Utilities

import { pick, omit } from "@trdev20/js-utils";

pick({ a: 1, b: 2, c: 3 }, ["a", "c"]); // => { a: 1, c: 3 }
omit({ a: 1, b: 2, c: 3 }, ["b"]); // => { a: 1, c: 3 }

Validators

import { isString, isNumber, isArray, isObject, isPrime, isOdd, isEven } from "@trdev20/js-utils";

isString("hello"); // => true
isNumber(123); // => true
isArray([1, 2, 3]); // => true
isObject({}); // => true
isPrime(7); // => true
isOdd(3); // => true
isEven(4); // => true

Array Operators

• uniqueArr<T>(arr: T[]): Returns array with unique items
• chunkArr<T>(arr: T[], size: number): Splits array into chunks
• intersection<T>(arr1: T[], arr2: T[]): Returns common elements
• difference<T>(arr1: T[], arr2: T[]): Returns elements in arr1 not in arr2

Object Operators

• pick<T, K extends keyof T>(obj: T, keys: K[]): Creates object with selected properties
• omit<T, K extends keyof T>(obj: T, keys: K[]): Creates object without specified properties

Validators

• isString(value: unknown): Checks if value is string
• isNumber(value: unknown): Checks if value is number
• isArray(value: unknown): Checks if value is array
• isObject(value: unknown): Checks if value is object
• isPrime(value: number): Checks if number is prime
• isOdd(value: number): Checks if number is odd
• isEven(value: number): Checks if number is even
• isEmptyString(value: string): Checks if string is empty
• isEmptyArray(value: unknown[]): Checks if array is empty
