Package Exports

stringmap

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (stringmap) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

stringmap.js

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

Examples

Available in examples.js

var StringMap = require("stringmap");

var sm1 = new StringMap();
sm1.set("greeting", "yoyoma");
sm1.set("check", true);
sm1.set("__proto__", -1);
console.log(sm1.has("greeting")); // true
console.log(sm1.get("__proto__")); // -1
sm1.delete("greeting");
console.log(sm1.keys()); // [ 'check', '__proto__' ]
console.log(sm1.values()); // [ true, -1 ]
console.log(sm1.items()); // [ [ 'check', true ], [ '__proto__', -1 ] ]
console.log(sm1.toString()); // {"check":true,"__proto__":-1}

var sm2 = new StringMap({
    one: 1,
    two: 2,
});
console.log(sm2.map(function(value, key) {
    return value * value;
})); // [ 1, 4 ]
sm2.forEach(function(value, key) {
    // ...
});
console.log(sm2.isEmpty()); // false
console.log(sm2.size()); // 2

var sm3 = sm1.clone();
sm3.merge(sm2);
sm3.setMany({
    a: {},
    b: [],
});
console.log(sm3.toString()); // {"check":true,"one":1,"two":2,"a":{},"b":[],"__proto__":-1}
