Job Prep Flashcards
Tell me about youself
I recently graduated from a full stack coding Bootcamp called learningfuze, there I was working in an environment that simulated a real-world working environment working under the mentorship of senior developers. I come from a background in Information Systems and worked as a manager for a restaurant during my teen years all the way through college. I decided to chase my dreams of becoming a software developer when I first took a college course in Python.
What technologies are you familiar with?
I have a strong understanding of HTML, CSS, Javascript, and React, and have also worked with technologies such as Node.js, Express, PostgreSQL, Bootstrap, etc.
What is the difference between == and === ?
== - is loosely equals, meaning that it will convert the comparing values to the same datatype such as (‘1’ and 1) and will give you boolean true because it converts to same data type.
=== is strictly equals, we want to use this always so it avoids any errors from data being converted to the same datatype. If you compare string 1 to number 1 it will give you false since they are not the same data type as opposed to == converting those to the same data type.
What is the difference between var, const, and let?
Let - block-scoped, you can change the value over time
Const - block-scoped, cannot be redeclared or reassigned
Var - function-scoped
