Tiny TypeScript utils: wait(), arrayFromIterator(), chanceRandom(), equal() and more

API

• formatNumber(x: number): string
• reportMemory(): void
• random(min: number, max: number): number
• arrRandom(arr: any[]): any
• chanceRandom(elements: { [key: string]: number }): string
• equal(v1: any, v2: any): boolean
• quickTextCompare(text1: string, text2: string): boolean
• includesAll(arr: any[], values: any[]): boolean
• arrayFromIterator(iterator: IterableIterator<any>): any[]
• async wait(time_ms: number): Promise<void>

Requirements

• NodeJS, recommended v18 or newer

Setup

• Install utils via npm:

npm i @easy-ds-bot/utils

• Use utils:

// file.js, type: CJS
const { random, arrRandom } = require("@easy-ds-bot/utils");
let colors = ["red", "green", "blue"];
console.log(`Random int: ${random(1, 100)}, random color: ${arrRandom(colors)}`);
//> Random int: 32, random color: blue
//...it is one of 300 variants

...or:

// file.js, type: ESM
import { random, arrRandom } from "@easy-ds-bot/utils";
let colors = ["red", "green", "blue"];
console.log(`Random int: ${random(1, 100)}, random color: ${arrRandom(colors)}`);
//> Random int: 32, random color: blue
//...it is one of 300 variants
