Питання-відповіді

What are the key features of ES6 in modern JavaScript development?

ES6 introduced features such as arrow functions, template literals, classes, and destructuring assignments to enhance JavaScript development.

How does ES6 arrow functions differ from regular JavaScript functions?

Arrow functions have a more concise syntax compared to regular functions and also automatically bind the `this` value from the surrounding code.

What are template literals in ES6?

Template literals allow for easier string interpolation in JavaScript by using backticks (`) to wrap the string and placeholders for variables within ${}.

How does ES6 improve object-oriented programming in JavaScript?

ES6 introduced classes and constructors to make it easier to create and manage object instances, bringing more structure to object-oriented programming in JavaScript.

What is destructuring assignment in ES6?

Destructuring assignment allows you to extract values from arrays or objects and assign them to variables in a single, more compact syntax.

How can ES6 default parameters simplify function definitions?

You can set default values for function parameters directly in the function’s parameter list, reducing the need for explicit checks and providing fallback values if parameters are not provided.

What is the purpose of the spread operator (…) in ES6?

The spread operator allows you to expand an array or object for use in places where multiple arguments or elements are expected, making it easier to work with collections in JavaScript.

How does ES6 handle asynchronous programming with Promises?

ES6 introduced Promises as a way to handle asynchronous operations more effectively, allowing for cleaner code and better error handling compared to traditional callback-based approaches.

What are ES6 modules and how do they improve code organization?

ES6 modules provide a standardized way to organize and structure code by allowing you to export and import functions, classes, or variables between files, making it easier to manage dependencies and maintainability.

How does ES6 help with functional programming in JavaScript?

ES6 introduced features like arrow functions, map, reduce, and filter methods that align with functional programming principles, enabling developers to write more concise and expressive code in a functional style.
