Test name	Executions per second
Object.fromEntries	1311.7 Ops/sec
Reduce (reuse object)	2652.8 Ops/sec
Reduce (recreating object)	45.2 Ops/sec
Map	1212.0 Ops/sec
Reduce (assigning into reused object)	269.5 Ops/sec

Script Preparation code:

var data = { ...Array.from(Array(10000).keys()) };

Tests:

Object.fromEntries
Object.fromEntries(Object.entries(data).map(([key, value]) => [key, value]));
Reduce (reuse object)
Object.entries(data).reduce((acc, [k, v]) => { acc[k] = v; return acc; }, {});
Reduce (recreating object)
Object.entries(data).reduce((acc, [k, v]) => ({ ...acc, [k]: v }), {});
Map
Object.entries(data).reduce((acc, [k, v]) => { acc.set(k, v) return acc; }, new Map());
Reduce (assigning into reused object)
Object.entries(data).reduce((acc, [k, v]) => Object.assign(acc, { [k]: v }), {});
