Benchmark: array-group-test

Script Preparation code:

var groups = [['E', 'E_T'], ['T', 'T_T']];

var elements = [
  { t: 'E', cls: 'E' },
  { t: 'EU', cls: 'E_T' },
  { t: 'EC', cls: 'E_T' },
  { t: 'B', cls: 'B' },
  { t: 'T', cls: 'T' },
  { t: 'TU', cls: 'T_T' },
];

Tests:

A (2 cycles)
const temp = {}; for (const cGroup of groups) { const key = cGroup.join(); for (const el of elements) { if (!cGroup.includes(el.cls)) { continue; } if (!temp[key]) { temp[key] = [el]; } else { temp[key].push(el); } } } const res = []; for (const cGroup of Object.values(temp)) { res.push(cGroup); }
B (1 cycle + map)
const keyToIdx = {}; const res = []; for (const cGroup of groups) { const key = cGroup.join(); for (const el of elements) { if (!cGroup.includes(el.cls)) { continue; } const groupIdx = keyToIdx[key]; if (groupIdx > -1) { res[groupIdx].push(el); } else { keyToIdx[key] = (res.push([el]) - 1); } } }
