There are a hundred books on JavaScript and I don’t want to write another one into that pile, but there is a dearth of a revision material that a developer could skim through maybe right before an interview. This book addresses just that. A ready reckoner, a one stop look to refresh your fundamentals on your kindle, while waiting for your turn to be interviewed at a company.
These are very fundamental concepts any JavaScript Developer should understand and are usually the front run questions any interviewer would ask in a level 1 technical interviews of JavaScript. This is documented as crisp as possible with the main intention to only review the basics in less than 10 minutes. No JavaScript technical interview is complete without at least a few of these fundamental concepts or different flavor questions on these same concepts.
This book explains the very fundamental concepts like What is JavaScript ? Is JavaScript Case Sensitive ? What are the datatypes in JavaScript ? What is a prototype ? What are function closures ? What is variable hoisting ? What is function hoisting ? What is the difference between == and === operators ? What is call() and apply() ? What is context switching in JavaScript ? What is function chaining? What is the difference between let a=10; var a=10; and a=10; ? What is scope in JavaScript ? How does scope change ? and a lot more questions and the most simplest way to answer them.
Also don't forget to have a look at some of the really interesting code snippet questions that tests the very basics of your understanding on these concepts !
