Test name
Executions per second
naive compare
0.1 Ops/sec
compare with pop
0.1 Ops/sec
Script Preparation code:
var watched = []; var ignored = []; for(let i = 0; i < 100000; i++){watched.push({programId:Math.random()});} for(let i = 0; i < 100000; i++){ignored.push({programId:Math.random()});}
Tests:
naive compare
watched.filter(obj => { return !ignored.some(item => item.programId === obj.programId); });
compare with pop
watched.filter(wObj => !ignored.some((iObj, ndx) => { if (iObj.programId === wObj.programId) { ignored[ndx] = ignored.pop(); return true; } return false; }) );
