Posts: 10,222. Grill marks have been discussed many times over the years. Sure, they are pretty and make a really strong statement about the meat, but many high-dollar restaurants reportedly draw their grill marks on with a meat-marker, while others brush on a coat of sugar water prior to it hitting the hit grill.
How to call Function ? You call a Function procedure by using the procedure name, followed by the argument list in parentheses, in an expression. You can omit the parentheses only if you are not supplying any arguments. However, your code is more readable if you always include the parentheses.
Strangely, I havenât found any good introductions to callback functions onlineâI mainly found bits of documentation on the call() and apply() functions, or brief code snippits demonstrating their useâso I decided to try to write a simple introduction to callbacks myself. Functions are objects. To understand callback functions you first have to understand regular functions. This might seen like a âduhâ thing to say, but functions in Javascript are a bit different than (for example) methods in Java. Functions in Javascript are first-class, and are actually objects.
