Limit concurrency of a function returning a promise.
var throttle = require("f-throttle") var throttledFn = throttle(concurrency, anyFn)
throttleFn functions like
anyFn, but throttled to a concurrency of
concurrency, where concurency is a number equal or higher than one.
throttledFnreturns a promise.
anyFnmust return a promise. If it does not, the promise returned by
throttledFnwill be rejected.
- You may pass any number of arguments
- Function context is preserved, so can work for when throttling a function that's a method for an object.
- When you throttle a function to a concurrency of 1, this results in execution in a serial fashion.
