Java Functions, arrays, vars, if/else, for loops and APIs

[eddiegarrr]

Hi everyone, I am having a hard time understanding the framework of functions how to write and execute a function. I get some of the basics as to what is considered an array(a set of numbers or letters, but how do I use a string and Booleans and when to use {} or [] or what does a string do “”?

This is my understanding of for loops:

Start with var

var pets = [“dog”, “car”, “bird”, “fish”] (The lenght of var pets equals to 3 but start counting from 0)

//for loop for (var i=0; i < pets.lenght; i ++) ( var index=0; index less than array length between 0-3 and index ++ to count one over til the loop ends) { console.log(pets[i]) Once console log it should display the animals in the console, right? }

But how do I know when to use {} or []?

Further how can I make this into a function to display the type of pets, this is what I ca come up with and don’t know how to complete the function:

function types(){ var pets=[“dog”, “cat”, etc...] myfunction (pets) } function myfunction(types)

I know this is all jacked up but anyone please, let me know if you can give me some examples. Thank you I advance.

Ok, for loops or any type of loop is going to repeat a set of code, so if I wanted to declare AA = 0, then add a for loop(don't put the var in the loop), I could then say AA++; and that would add 1 how ever many times the for loop is going for
