Hands-On Data Structures and Algorithms with JavaScript

Sets and Arrays

Creating and running suites is very easy thanks to the benchmark tool. All we will need is to set up our sets-arr.js file, and we are good-to-go:

var Benchmark = require("benchmark");var suite = new Benchmark.Suite();var set = new Set();var arr = [];for(var i=0; i < 1000; i++) {   set.add(i);   arr.push(i);}suite   .add("array #indexOf", function(){      arr.indexOf(100) > -1;   })   .add("set #has", function(){      set.has(100);   })   .add("array #splice", function(){      arr.splice(99, 1);   })   .add("set #delete", function(){      set.delete(99);   })   .add("array #length", function(){      arr.length;   })   .add("set #size", function(){      set.size;   })   .on("cycle", function(e) {      console.log("" + e.target);   })   .run();

You can see that the setup is pretty self-explanatory. ...
