Function filterWithKey

The same concept as Array.filter(), but for object keys

Example

import * as P from "flurp/pojo";

const moreThanTwoChars = P.filterWithKey<Record<string, string>>((s: string) => s.length > 2);
moreThanTwoChars({ x: 3, yy: -4, zzz: 5 });         // { zzz: 5 }

const keyEqualsValue = P.filterWithKey<Record<string, string>>((k: string, v: string) => k === v);
keyEqualsValue({ x: "x", y: "weasel", z: "z" })   // { x: "x", z: "z" }
