stringset

0.2.1 • Public • Published

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.

The API is created to be as close to the ES6 Set API as possible. Prefer ss.remove("key") for deleting a key. ES6 Set uses set.delete("key") instead and for that reason ss['delete']("key") is available as a stringset alias as well. Never do ss.delete("key") unless you're certain to be in the land of ES5 or later.

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.remove("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__"}
