Benchmark: buffer operations

Script Preparation code:

var buffer_to_fill = new Array(0);
var buffer_to_empty = new Array(1000);
buffer_to_empty.forEach(item => item=Math.floor(Math.random()*1000));

Tests:

push_foreach
buffer_to_empty.forEach(item => buffer_to_fill.push(item));
concat
buffer_to_fill = buffer_to_fill.concat(buffer_to_empty);
splice
buffer_to_empty = buffer_to_empty.splice(0,50);
shift
while (buffer_to_empty.length>50) { buffer_to_empty.shift(); }
push_for_loop
for (var i=0; i<buffer_to_empty.length; i++){ buffer_to_fill.push(buffer_to_empty[i]); }
