TOAST UI

Let's imagine a day without touch and click. How would it be? I can't imagine a day without these two actions now. When I was a user, I used it unconsciously and never thought deeply about the relationship between these two actions. It wasn't until I became a front-end developer and encountered issues caused by the difference between touch and click that I started to think about the relationship between the two actions.

Years have passed since ES2015 came out in June 2015. While writing the previous weekly picks, I thought, "Is there any ES2015 syntax I'm not using, like Proxy or Reflect?". The first things that came to mind were WeakMap and WeakSet.

I began to wonder why Reflect was used to implement the Vue 3 Reactivity's Proxy trap. Upon Googling, only thing I could find was how to use the Proxy's handlers or other tutorials, so I decided to take a deeper look into it. This article reviews the basic concepts of Proxy and Reflect as well as explore why Reflect was used with the Proxy.

Time zones and Summer Time have always been a mountain of issues and considerations for front end development.

Proxy is a feature newly introduced in ES2015. Although IE11 does not support Proxy, other modern browser are compatible with it. While Proxy cannot be transpiled using Babel, Google offers a polyfill so that it can be compatible with IE11.
