The Push to Ban Ransom Payments Is Gaining Momentum
Ransomware costs victims an estimated $30 billion per year and has gotten so out of control that global support for banning payments is gaining momentum.

🎯A collection of polyfills that focuses on being ultra light-weight 🎯
Set of polyfills for Map
, Set
, WeakMap
and other standard functions that could be missing in some legacy runtime environnement.
Focus is placed on bundle size rather than performance and transparency.
The goal is to allow our code to run on older browsers without significantly increasing the bundle size by adding exhaustive polyfills that in 95% of the cases won't be necessary.
The classes exposed only implement the more common features of their native counterpart, it does so in a very naïve and inefficient way to keep the code as short as possible.
As you would expect the polyfills will only be used when the native classes are missing.
//Example with map.
import { Polyfill as Map, LightMap } from "minimal-polyfills/Map";
// Explicitly define the type of your variable to make it clear
// that you are using a subset of Map...
const map: LightMap<string, number>= new Map();
//...or let the type be inferred.
const map = new Map<string, number>();
import { Polyfill as Set, LightSet } from "minimal-polyfills/Set";
//WARNING: If not natively supported WeakMap will only be a simple Map that will keep string references of it's keys.
import { Polyfill as WeakMap } from "minimal-polyfills/WeakMap";
import { Polyfill as WeakSet } from "minimal-polyfills/WeakSet";
import "minimal-polyfills/Array.prototype.find";
import "minimal-polyfills/String.prototype.startsWith.ts";
import "minimal-polyfills/Array.from.ts";
import "minimal-polyfills/ArrayBuffer.isView.ts";
import "minimal-polyfills/Object.fromEntries";
import "minimal-polyfills/Object.is.ts";
import "minimal-polyfills/Object.assign.ts";
Thanks to Stackblitz you can try this lib with within your browser like if you where in VSCode.
