Runs an array of functions in series, each passing their results to the next in the array. However, if any of the functions pass an error to the callback, the next function is not executed and the main callback is immediately called with the error.
For browsers and node.js.
- Just include async-waterfall before your scripts.
npm install async-waterfallif you’re using node.js.
component install es128/async-waterfallif you’re using component(1).
bower install async-waterfallif you’re using Twitter Bower.
- tasks - An array of functions to run, each function is passed a
callback(err, result1, result2, ...)it must call on completion. The first argument is an error (which can be null) and any further arguments will be passed as arguments in order to the next task.
- optionalCallback - An optional callback to run once all the functions have completed. This will be passed the results of the last task's callback.
var waterfall = ;;
// component(1)var waterfall = ;;// Default:window;
