Question

ARRAYS - JavaScript Web Development

What are two ways an online store website might use an array and why this is a good technique and two ways that conditional statements (if, if - then, if - if - then - else, or switch case) help to streamline your visitor's experience? Please include code showing what the two arrays might look like.

Answer 1

Arrays can be used in a variety of purposes in a website.

Like to store a list of shopping items, or the total available items in the store currently.

We can store the items as strings, or their positions as numbers or both as an array of array.

Like

array = [["milk", 1], ["bread", 2], ["eggs", 3]]

Conditional statements :

If, if then, if else,

If a user is applying some filters. these statements will be helpful like :

1. On price : If (price of item) > 200 & < 1000, show

2. On listings: If the number of items is less than 20, show

else split into pages

3. Payments : if item is in cart, then show discounted price

else show the normal price
