Questions and Answers related to JavaScript Development

What are the pros and cons of using JavaScript in the backend?

if_42_dispute_and_arguments_1172644“Javascript is the language of the Web (I assume you’re referring to backend web development). As such, prior knowledge of it, assuming you are of a frontend background (second assumption), makes the transition from client side work to server side work relatively smooth. There is no need picking up either of PHP, Python, Ruby, etc., to get started.”

What are some simple strategies to enhance JavaScript performance?

if_22_-_SEO_Performance_1082145“I’ll take my own stab at this to give an example of what I’m looking for: This may be obvious: Don’t Repeat Yourself. If you find yourself writing very similar pieces of code numerous times in a row, it’s a common performance enhancement to abstract that code into a function that can accept parameters and vary it’s output. As a general rule: less code == better performance. Pass necessary objects into functions, rather than relying on higher-scoped variables…”

How do JavaScript closures work?

if_delete_remove_close_exit_trash_200319“A Closure is a feature of the Javascript language, something that happens as part of how language was designed. Closures are part of the language, not a technique. In short, when you call a nested function in Javascript. Javascript remembers, or encloses any variables called within the execution context of the parent function, making them available to the function nested within.”

What are the intuitive explanation for JavaScript bind, apply and call functions?

if_strategy_970760“Both call and apply call a function with a certain this value and arguments. The difference between these two is the fact that apply takes an argument list as the second argument and call receives arguments separately. On the other hand, bind returns a new function (which cannot be bound again) that will always have the specified this as well as the supplied arguments.”
