The rapid digitalization of the world means businesses of all kinds are investing in web development and programming-related fields. Although web development is mostly led by full-stack, front, and back-end development, several new platforms and methods ensure more efficient results.
Mean stack is one such platform that has garnered a significant amount of popularity in the past few years. It is an open-source platform that allows programmers to use JavaScript-based technologies, thereby allowing them to enjoy the advantages of various web development technologies in one go.
As the mean stack is the up-and-coming web development platform, recruiters often ask questions about the platform to pick and choose the best programmers from potential candidates.
Here is a list of frequently asked mean stack interview questions and their probable answers:
1. What is MongoDB used for?
It is used for storing huge volumes of data. After storing data, MongoDB further saves it in binary JSON format after completing the compilation and documentation process.
2. What is ExpressJS used for?
ExpressJS supports Node.js projects as it manages the workflow between front-end web development and database, thereby facilitating a smooth transfer of data.
3. What is Angular JS used for?
Programmers use it to teach HTML as the template language.
4. What is the purpose of Node.js?
Node.js facilitates the development of server-side and networking applications.
5. What are the IDEs commonly used for the development of Node.js?
Atom, Cloud9, Eclipse, and Komodo IDE are the most frequently used IDEs.
6. What is REPL in Node.js?
Read Even Print Loop is a simple feature that understands the commands given and prints them.
7. What is Mongoose?
It is an Object Document Mapper used to define objects with the help of a strongly-typed schema.
8. What is DATA modeling?
It creates a model type for the data generated to create an organized database.
9. What does Scope in JavaScript mean?
Each function within JavaScript has a scope that has a collection of variables and rules that define the meaning of the function.
10. What is the difference between binary and linear research?
Linear research lists items searched according to their sequence, while binary research does not follow a set sequence.
Although the questions mentioned are not all that can be asked in an interview, they cover the basics of Mean Stack in detail.
