Features and Usage

• forEachAsync(callback: Func<T, Promise>, thisArg?: any): Promise;

await myArray.forEachAsync(async (item) => {
  await doSomethingAsync(item); 
});

• everyAsync(predicate: Func<T, Promise>, thisArg?: any): Promise;

const isEvery = await myArray.everyAsync(async (item) => {
  return await doSomethingAsync(item); 
});

• someAsync(predicate: Func<T, Promise>, thisArg?: any): Promise;

const isSome = await myArray.someAsync(async (item) => {
  return await doSomethingAsync(item); 
});

• filterAsync(predicate: Func<T, Promise>, thisArg?: any): Promise<T[]>;

const filteredArray = await myArray.filterAsync(async (item) => {
  return await doSomethingAsync(item); 
});

• findAsync(predicate: Func<T, Promise>, thisArg?: any): Promise;

const foundItem = await myArray.findAsync(async (item) => {
  return await doSomethingAsync(item); 
});

• findIndexAsync(predicate: Func<T, Promise>, thisArg?: any): Promise;

const foundIndex = await myArray.findIndexAsync(async (item) => {
  return await doSomethingAsync(item); 
});

• mapAsync<T, T1>(callback: Func<T, Promise>, thisArg?: any): Promise<T1[]>;

const mappedArray = await myArray.mapAsync(async (item) => {
  return await doSomethingAsync(item); 
});
