Find() vs Get() (v2)

Revision 2 of this benchmark created on

Description

Get seems to be more performant in cases smaller than 100 matching 100. But it switches over to Find when matching 100 against 1000

Setup

const legends = Array.from({ length: 100 }, (_, i) => ({ name: `legend${i}`, visible: Math.random() < 0.5 }));
// const metaLegends =[ { name: `legend${77}`, visible: Math.random() < 0.5}, { name: `legend${88}`, visible: Math.random() < 0.5}, { name: `legend${99}`, visible: Math.random() < 0.5} ];
const metaLegends = Array.from({ length: 100 }, (_, i) => ({ name: `legend${i}`, visible: Math.random() < 0.5 })).sort(() => Math.random() - 0.5);
const newLegends = [];
