Script Preparation code:

var objectItem = {
  a:1,
  b:2,
  c:3,
}

var arrayItem = new Float32Array([1,2,3]);

var output = new Float32Array(300);

Tests:

copy from object
var index = 0; for(var i = 0; i < 300/3; i++) { output[index++] = objectItem.a; output[index++] = objectItem.b; output[index++] = objectItem.c; }
copy from floatArray
var index = 0; for(var i = 0; i < 300/3; i++) { output[index++] = arrayItem[0]; output[index++] = arrayItem[1]; output[index++] = arrayItem[2]; }
