Filter
function fill(c) { return c.filter ( function(v) { for(let x=0;x<d.length;x++) { if(d[x].id == v.id){ return true } } }) } console.log(fill(c));
for loop
var zzz=[]; for(let y=0;y<d.length;y++) { let v=c[y]; for(let x=0;x<d.length;x++) { if(d[x].id == v.id){ zzz.push(v) } } } console.log(zzz);
