TYPESCRIPT

async await forEach

// Array.prototype.forEach is not designed for asynchronous code.
// Instead use await Promise.all to process all in parallel if the order doesn't matter.
await Promise.all(array.map(async (element) => {
  await someFunction(element);
}))

ts await foreach loop

async function printFiles () {
  const files = await getFilePaths();

  await Promise.all(files.map(async (file) => {
    const contents = await fs.readFile(file, 'utf8')
    console.log(contents)
  }));
}

foreach async typescript

  for (const file of files) {
    const contents = await fs.readFile(file, 'utf8');
    console.log(contents);
  }
 

typescript foreach async await

export async function asyncForEach<T>(array: Array<T>, callback: (item: T, index: number) => void) {
        for (let index = 0; index < array.length; index++) {
            await callback(array[index], index);
        }
    }

await asyncForEach(receipts, async (eachItem) => {
    await ...
})

js await in foreach

// Javascript will proceed to call the code that comes AFTER the forEach loop, 
// and then execute the code within the loop. This is because forEach is not 
// async-aware. YOU CANNOT USE AWAIT IN FOREACH. Use a regular for loop instead.
