During the “4/6, Functions for organization” exercise, I arrived at the last “I’d like 3 sandwiches, 2 fries, and 2 triple ice cream scoop, please!”… When making the fries without functions, I actually accidently added an extra fry. A simple mistake I really didn’t think would happen, but knew WITH the functions button, my error would not have occurred. Thank you for this basic and valuable lesson on functions.
Aspiring coder here. Just trying to string together what I’ve learnt. Would anyone mind telling what the difference is between a function and variable? Thank you in advance.
They are really quite different from one another. A variable is a label to which we can assign any object, which in JavaScript includes anonymous functions, since they too are objects.
A function is an isolated block of code that we can call upon repeatedly anytime during the run session. Some functions perform heavy lifting and others perform relatively simple utility tasks.
foo = function (parameter) {
// code body
return expression or value
}
Above, foo is the variable to which we have assigned an anonymous function expression. We can execute (call) the function by referring to its variable name…
console.log(foo(argument))
Variables are not objects, per se. They refer to objects so that we can access them either to poll (get their data) or update (modify their data).
We learn more about functions as we move forward, but variables once we understand them to be simply labels, won’t require much review or practice. They are used all the time so one gets quite used to them.
Functions
Functions are created to make the repetitive task quick. Humans don’t like to work on repetitive task, and also make mistakes as get bored on doing same task again and again. So repetitive task in a program are done using functions, whereas the programmer can focus on new task.
If a person keeps on doing restive task his life would spend without achieving much. Whereas if once a task is mastered by the programmer, it can be automated and can be let on machine to be done, and that’s what functions do.
Please correct if my statement is wrong,
Tx.
Functions are design to create repetitive task to avoid doing the same task over and over while variables are labels to which we can assign object… i stand to be corrected
