Java source code:
k = i + j;

May compile to Java bytecode:
iload_0 
iload_1 
iadd 
istore_2

And may turn into Dalvik VM code:

rednaxelafx

function isPlainObject(o) {
  return o && toString.call(o) === '[object Object]' && 'isPrototypeOf' in o;
}

function isArray(o) {
  return toString.call(o) == '[object Array]';
}

function objectToString(val) {
  var INDENT = '  ';
