By far is how values get passed into functions.
const firstName = 'Wes'; function sayHello(name) { console.log(`Hello ${name}`); } sayHello(firstName);
Why is it name and not firstName?!
name
firstName
Seems to simple to anyone programming for a while, but it's often a cause for confusion in my students.
References (arrays, objects) VS values (strings, numbers) is another one.
Truthy/falsy was another one but I've got pretty good at explaining that :)
Beginner here, is this because whatever you put in the brackets after sayHello is what is passed, 'name' is essentially a placeholder for the value you are passing into it?
Correct. name is the parameter scoped to that function.
That's really good info. I never would have guessed that. Thanks for answering!
This brings me back. I remember this tripping me up early on. It lead to some behavior like always using the same name for both things just in case.
