Functions

partition()

partition<T>(arrayOrPromise, callbackfn): Promise<[T[], T[]]>

Type Parameters

Type Parameter
T

Parameters

Parameter	Type	Description
arrayOrPromise	T[] | Promise<T[]>	The array or Promise of an array to iterate over.
callbackfn	(value, index, array) => boolean | Promise<boolean>	A function that accepts up to three arguments. The partition method calls the callbackfn function one time for each element in the array.

Returns

Promise<[T[], T[]]>

A Promise that resolves with an array containing two arrays: the first array contains the elements that satisfy the condition, and the second array contains the elements that do not satisfy the condition.

Example

const array = [1, 2, 3, 4];
const result = await partition(array, (value) => value > 2);
console.log(result); // Output: [[3, 4], [1, 2]]
