To rock the interview to achieve what you deserve and to improve your concepts about front end technologies, I have consolidated a list of questions and answers. It’s a one stop solution for front end interview process.
Being a SOLID developer in JS isn’t so as straight forward as in other languages. Some developers consider functional approach. Others chose OOP style. Some stand in both line. And other think that having class is wrong and redundant and prefer factories. But still, SOLID principles are the basic pillars of object oriented programming.
But what are they?
What’s the Difference Between Class & Prototype Inheritance?
This can be a tricky question, and you’ll probably need to defend your answer with follow-up Q&A, so pay special attention to learning the differences, and how to apply the knowledge to write better code.
One of the most important aspects of writing maintainable code is being able to notice the repeating themes in that code and optimize them. This is an area where knowledge of design patterns can prove invaluable.
I take a look at a number of popular JavaScript design patterns and explore why certain patterns may be suitable for your projects.
Many of us are using promises without really understanding them.
The main point is that one object can be prototype of another object. That means if property isn’t found in the object - than it takes from prototype object. In JavaScript this implementation is at the language level.
Funny to hear when developer says that JS does not have types =) Let’s see how to distinguish them right.
Describe different approaches to define and call functions
