Standard Functions

mapAny

Usage:

import { mapAny } from '@bconnorwhite/for-any';

let array = [1, 4, 9, 16];
let item = 5;

let callback = (x)=>x*2;

let arrayResult = mapAny(array, callback);
console.log(arrayResult);
// output: [2, 8, 18, 32]

let itemResult = mapAny(item, callback;
console.log(itemResult);
// output: 10

Types:

function mapAny<T, V>(
  any: (T | V[]),
  callback: (currentValue: (T | V), index?: number, array?: (T | V)[]) => any,
  thisArg?: any
): (any | any[]);

filterAny

Example usage:

import { filterAny } from '@bconnorwhite/for-any';

let array = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];
let item1 = 'test';
let item2 = 'testing #2';

let callback = (x)=>x.length > 6;

let arrayResult = filterAny(array, callback);
console.log(arrayResult);
// output: ["exuberant", "destruction", "present"]

let item1Result = filterAny(item1, callback);
console.log(item1Result);
// output: undefined

let item2Result = filterAny(item2, callback);
console.log(item2Result);
// output: "testing #2"

Types:

function filterAny<T, V>(
  any: (T | V[]),
  callback: (element: (T | V), index?: number, array?: (T | V)[]) => boolean,
  thisArg?: any
): (T | V[] | undefined);

reduceAny

Example usage:

import { reduceAny } from '@bconnorwhite/for-any';

let array = [1, 2, 3, 4];
let item = 5;

let callback = (accumulator, currentValue) => accumulator + currentValue;

let arrayResult = reduceAny(array, callback);
console.log(arrayResult);
// output: 10

let itemResult = reduceAny(item, callback);
console.log(itemResult);
// output: 5

Types:

function reduceAny<T, V>(
  any: (T | V[]),
  callback: (accumulator: any, currentValue: (T | V), index?: number, array?: (T | V)[]) => any,
  initialValue?: any
): any;

forEachAny

Example usage:

import { forEachAny } from '@bconnorwhite/for-any';

let array = ['a', 'b', 'c'];
let item = 'd';

let callback = (element)=>console.log(element);

forEachAny(array, callback);
// output: "a"
// output: "b"
// output: "c"

forEachAny(item, callback);
// output: "d"

Types:

function forEachAny<T, V>(
  any: (T | V[]),
  callback: (element: (T | V), index?: number, array?: (T | V)[]) => void,
  thisArg?: any
): void;

findAny

Example usage:

import { findAny } from '@bconnorwhite/for-any';

let array = [5, 12, 8, 130, 44];
let item1 = 15;
let item2 = 5;

let callback = (element) => element > 10;

let arrayResult = findAny(array, callback);
console.log(arrayResult);
// output: 12

let item1Result = findAny(item1, callback);
console.log(item1Result);
// output: 15

let item2Result = findAny(item2, callback);
console.log(item2Result);
// output: undefined

Types:

function findAny<T, V>(
  any: (T | V[]),
  callback: (element: (T | V), index?: number, array?: (T | V)[]) => boolean,
  thisArg?: any
): (T | V | undefined);

Extended Functions

stringReduceAny

Example usage:

import { stringReduceAny } from '@bconnorwhite/for-any';

let array = ["This", "forms", "a", "sentence"];
let item = "Nice";

let callback = (currentValue, index, array) => {
  return currentValue + ((index === array.length-1) ? "." : " ");
}

let arrayResult = stringReduceAny(array, callback);
console.log(arrayResult);
// output: "This forms a sentence."

let itemResult = reduceAny(item, callback);
console.log(itemResult);
// output: "Nice."

Types:

function stringReduceAny<T, V>(
  any: (T | V[]),
  callback: (currentValue: (T | V), index?: number, array?: (T | V)[]) => string,
  initialValue: string = ""
): string;

Utility Functions

asArray

Example usage:

import { asArray } from '@bconnorwhite/for-any';

let array = [5, 12, 8, 130, 44];
let item = 15;

let arrayResult = asArray(array);
console.log(arrayResult);
// output: [5, 12, 8, 130, 44]

let itemResult = asArray(item);
console.log(itemResult);
// output: [15]

Types:

function asArray<T>(any: (T | T[])): T[];
