Svelte Quiz

What is a Svelte component?

• A Svelte component is a programming language

• A Svelte component is a reusable piece of code that encapsulates HTML, CSS, and JavaScript logic to create interactive user interfaces.

• A Svelte component is a type of car

• A Svelte component is a type of fruit

Explain the role of the Svelte Compiler in Svelte development.

• The Svelte Compiler is responsible for executing Svelte code in the browser.

• The Svelte Compiler generates HTML templates for Svelte components.

• The Svelte Compiler transforms Svelte components into efficient JavaScript code.

• The Svelte Compiler converts Svelte components into CSS stylesheets.

How is Svelte syntax different from other frontend frameworks?

• Svelte uses JSX syntax like React

• Svelte shifts the work of rendering components from the browser to the build step.

• Svelte requires a runtime library to function

• Svelte relies heavily on virtual DOM

What are reactive statements in Svelte?

• Reactive statements in Svelte are static and do not update the DOM

• Reactive statements in Svelte are only triggered by user interactions

• Reactive statements in Svelte are used for server-side rendering

• Reactive statements in Svelte are expressions that automatically update the DOM when their dependencies change.

What is the purpose of the 'svelte:' prefix in Svelte syntax?

• To indicate reactivity in Svelte syntax.

• To specify CSS styles in Svelte syntax.

• To handle routing in Svelte syntax.

• To define JavaScript functions in Svelte syntax.

How does Svelte handle state management in components?

• Svelte uses context API for state management in components.

• Svelte relies on Redux for state management in components.

• Svelte uses props drilling for state management in components.

• Svelte uses reactive declarations to handle state management in components.

What are the key benefits of using Svelte over other frontend frameworks?

• Built-in routing capabilities

• Efficient compilation to vanilla JS at build time

• Automatic state management

• Support for TypeScript out of the box

Explain the concept of two-way binding in Svelte.

• Two-way binding in Svelte is a one-time operation

• Two-way binding in Svelte ensures that changes made to the state are reflected in the DOM, and vice versa.

• Two-way binding in Svelte is a feature exclusive to React

• Two-way binding in Svelte only updates the state but not the DOM

What is the virtual DOM and how does Svelte utilize it?

• Svelte uses a virtual DOM similar to React and Vue

• The virtual DOM in Svelte is a separate layer that updates the actual DOM

• Svelte relies on a virtual DOM for server-side rendering

• Svelte compiles components to imperative code that directly manipulates the DOM, bypassing the need for a virtual DOM.

How does Svelte optimize the performance of web applications?

• Svelte uses jQuery for rendering web applications.

• Svelte compiles components at build time to efficient vanilla JavaScript code.

• Svelte interprets components at runtime resulting in slower performance.

• Svelte converts components to Angular code for optimization.
