stringset.js

A fast and robust stringset implementation that can hold any string items, including __proto__, with minimal overhead compared to a plain object. Works in node and browsers.

Examples

Available in examples.js

var StringSet = require("./stringset");

var ss1 = new StringSet();
ss1.add("greeting");
ss1.add("check");
ss1.add("__proto__");
console.log(ss1.has("greeting")); // true
console.log(ss1.has("__proto__")); // true
ss1.delete("greeting");
console.log(ss1.items()); // [ 'check', '__proto__' ]
console.log(ss1.toString()); // {"check","__proto__"}

var ss2 = new StringSet(["one", "two"]);
console.log(ss2.isEmpty()); // false
console.log(ss2.size()); // 2

var ss3 = ss1.clone();
ss3.merge(ss2);
ss3.addMany(["a", "b"]);
console.log(ss3.toString()); // {"check","one","two","a","b","__proto__"}

Installation
