A simple function that ensures that another function does not run too often. Subsequent calls will be delayed so they meet the criteria.
var Throttler = require("simple-throttler");
var t = Throttler(1000);
t(()=>console.log("1"));
t(()=>console.log("2")); // will run after 1s
t(()=>console.log("3")); // will run after 2s
