6 min readTo lift state up in React, you need to identify the common state that needs to be shared between multiple components. This state should be moved to the closest common ancestor of these components. By passing down the state and handlers as props to the child components, you can ensure that they stay in sync and share the same data across the application. This helps in reducing code duplication and ensures a single source of truth for the shared state.

To add an event listener to a DOM element, you can simply use the on: syntax followed by the event you want to listen to, like on:click or on:mouseover. You can then specify a function to be called when the event is triggered.Inside the event handler function, you can access the event object and use it to perform actions like updating component state or calling other functions.

5 min readTo map over an array and render components in React, you can use the map method provided by JavaScript arrays. This method allows you to iterate over each item in the array and return a new array with the transformed values.In React, you can map over an array of data and render components by using the map method inside the render method of your component. Within the map function, you can return the JSX for each component that you want to render based on the data in the array.

5 min readIn Svelte, you can pass props to a component by using the syntax prop={value}. These props can be accessed within the component using the export keyword. When importing a component that accepts props, you can pass them as attributes when including the component in your markup. This allows you to customize the behavior and appearance of the component based on the values passed to it.

4 min readIn React, you can conditionally render components by using JavaScript expressions within curly braces. You can create an if statement or ternary operator to check a condition and render different components based on that condition. Another way to conditionally render components is by using logical && operator to render a component only if a certain condition is true. You can also use if-else statements inside the render method to conditionally render components.
