Date tested: 4 months ago

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; }) );
