forEach
376758.1 Ops/sec
reduce
536424.4 Ops/sec
reduce spread

Script Preparation code:
var a = Array.from({length:100},()=>Math.random()); var b = [];
Tests:
forEach
a.forEach(e=>{if (e>0.5) b.push(e)});
reduce
b = a.reduce((a,c)=>c>0.5?a.concat(c):a,[])
reduce spread
b = a.reduce((a,c)=>c>0.5?[...a,c]:a,[])
