FAQs about being a Backend Developer
What programming languages are most commonly used in backend development?
The most commonly used programming languages in backend development include Java, Python, Ruby, PHP, and Node.js (JavaScript). The choice of language often depends on the project requirements, scalability needs, and the existing technology stack of the organization.
How do you ensure the security of a backend application?
To ensure backend security, developers implement authentication and authorization, use secure communication protocols like HTTPS, validate and sanitize user inputs, and regularly update dependencies. Additionally, they follow best practices such as encrypting sensitive data and conducting security audits.
What is the difference between REST and GraphQL APIs?
REST is an architectural style that uses predefined endpoints and HTTP methods, while GraphQL allows clients to request exactly the data they need with a single endpoint. GraphQL can reduce over-fetching and under-fetching of data, but REST is simpler and more widely adopted.
