React Dependency Arrays and Derived State

Dependency arrays are a very important part of React Hooks. They allow you to indicate what your effects, callbacks, and memos depend on so they can be recalculated only when necessary. For effects, this means your effects will be re-run every time one of your dependencies changes. The way that React determines if a dependency changes might not be the way you think, so you must be careful!

Instacart Receipt Analysis

I ordered a load of groceries from Kroger via Instacart a while back, and the Instacart shopper accidentally left the Kroger receipt in one of the shopping bags. I was confused because no other shoppers had given me the store receipt before. So i did some comparing between the Kroger receipt and the Instacart receipt to see how close the prices were between the two.

How Much Do Cars Really Cost?

I just sold my car. It was a 2002 Pontiac Bonneville. My parents bought it new back in August of 2002. I learned how to drive in that car, and I bought it from my parents in 2008 when I moved to Texas for a co-op job. I planned to keep that car until it wouldn't run anymore, so I tried to take as good care of it as possible.

Use exactly one <h1> tag. Use <h2> tags for other major headings. For headings that support content under your <h2> tags, use <h3> tags. For headings that support content under your <h3> tags, use <h4> tags.

Lazy Loading Images with ES5

Browsers typically load all of the images on the page as soon as possible. This is called eager loading. Sometimes, it's best if we wait to load images until we need them. This is called lazy loading. Lazy loading is a great technique for speeding up page load times and decreasing page sizes.
