The ecosystems where JavaScript runs have increased widely. Starting with the browsers, it has now extended to servers, smartwatches, and even in the field of AI or ML.

To access the global object in each environment, JavaScript has its own object model and provides a different syntax.

For example, in the browser, you can access the global object using these keywords window, self or frames.

console.log(window);    // Window {...}

Then, in the Node.js environment, these keywords — window, self or frames — will not work. Accessing them in the Node.js environment will throw an error — ReferenceError: window is not…

• Automatic critical CSS — No unnecessary code on your page, only renders the CSS when the components are injected into a page
• Dynamic styling — It adapts the styling of a component based on the props
• Supports Global CSS
• Supports Server Side Rendering (SSR)
• Automatic vendor prefixes
• Unique class names, that means no class names bugs

List of things I don’t know:

• Unix commands and bash — I can manage with ls, cd and the world-famous rm -rf Can manage with grep but for everything else, I’ve to lookup.
• CSS Methodologies — No BEMs, No OOCSS. I can do plain CSS. Currently using Tailwind CSS or styled-components. CSS-in-JS is the one I’m rocking now🤘
• TypeScript — Type checking in JavaScript is not…

Hooks were a new addition in the release of React 16.8. They let you use state and other React features without writing a class component.

The useEffect hook lets you perform side effects in function components

The useEffect hook is the Jack of all trades 👑 of the hooks. It’s the combination of componentDidMount, componentDidUpdate and componentWillUnmount. It's used for fetching the data when a component mounts, execute stuff when state or props change, Clean up stuff when the component unmounts. This useEffect hook can be really confusing 💡 until you understand or know how it works.

Recoil works and thinks like React.

Definition

Recoil is an experimental state management system for React by Facebook. It offers several out of the box abilities which are difficult to achieve with React ⚛️ alone.

Recoil lets you create a data-flow graph that flows from atoms through selectors and down into your React components.

Advantages

Recoil helps you eliminate the unnecessary re-renders which happens while using the Context API or Redux.

Consider a scenario where an app is using the Context API when the state in the context is changed, all the components in which even the data is not changed will…
