The purpose of Shadow DOM encapsulation is to prevent the “component styles” from affecting non-shadow nodes.

In January, I’ve been through so many technical interviews. Those questions tend to be about JavaScript, React, and browser APIs.

XHR (XMLHttpRequest) is one of the web APIs that allows browsers to interact with servers. Fetch API was introduced and deprecated the use.

The common misusages can result in an infinite rendering of a component, not updating states, or not rendering the components.

Intersection observer API can observe whether the elements are located within or at the intersection of the viewport.

My recommendation is always try to provide variables with types because type inference ends up using dynamic type when the analyzer doesn’t have enough information to infer a specific type.

I’d like to introduce the important skills as a developer other than coding, which I wanted to realize much earlier.
