Benchmark: filter-map vs reduce vs reduce with destructuring

Script Preparation code:

a=[];
for(i=0;i<1000;i++) a.push(Number(i)/1000);
var filtering=x=>(x*114514)%1>0.5;
var mapping=x=>x+0.1919;
var reducing=(acc,x)=>{
  var value=mapping(x);
  if(filtering(value)) acc.push(value);
  return acc;
}
var reducingWithDestructuring=(acc,x)=>{
  var value=mapping(x);
  if(filtering(value)) {
	return [...acc, value];
  }
  return acc;
}

Tests:

map-filter
a.filter(filtering).map(mapping);
reduce
a.reduce(reducing,[]);
reduce with desctructuring
a.reduce(reducingWithDestructuring,[]);
