If you are appearing at an interview as a junior JavaScript developer, you can have a bird’s eye view of the following topics:
What is JavaScript/Naming of JavaScript
How much you know about the discovery of JavaScript? Or if I say why this language is called JavaScript? There already exists a language called Java. So what’s the mystery behind the naming of JavaScript?
According to MDN web doc:
JavaScript was created in 1995 by Brendan Eich while he was an engineer at Netscape. JavaScript was first released with Netscape 2 early in 1996. It was originally going to be called LiveScript, but it was renamed in an ill-fated marketing decision that attempted to capitalize on the popularity of Sun Microsystem’s Java language — despite the two having very little in common. This has been a source of confusion ever since.
So JavaScript is a single-threaded, non-blocking, interpreted, client-side as well as server-side scripting language. It is single-threaded because it can perform a single task at a time. JavaScript has asynchronous behavior in nature.
