nodejs array foreach async code example
Example 1: 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)
}));
}
Example 2: C# foreach loop async but wait at end
public async Task RunAsync()
{
var tasks = new List<Task>();
foreach (var x in new[] { 1, 2, 3 })
{
var task = DoSomethingAsync(x);
tasks.Add(task);
}
await Task.WhenAll();
}
