Lists Rules: - Definition: A list is a collection of elements stored together. - Declare a variable with var - Use square brackets at the start and end of the list - Separate items with a comma - Use quotation marks for strings - To find the first element in the list: console.log(list name) - To find the last element in a list: console.log(list name[list name.length-1]) - Index → position in the list - insertItem → (list, index, element)→ adds an item anywhere in the list - appendItem→ (list, element) → adds an item at the end of the list - removeItem → (list, index)→ removes any item in the list Loops: - i++ → adds 1 each time until the condition is false - i- - → subtracted 1 each time until the condition is false Traversals: - < → less than sign → represents the minimum - > → greater than sign → represents the maximum - y/list.length → represents the average - y → is the sum of all the elements added together - + → addition symbol → represents addition
