The difference between Constructors vs. Literals in JavaScript

In JavaScript, we do have the freedom to get the same result in different ways. We can create strings, numbers, objects, arrays, etc. values using both constructors and literals approach. You can get the same values using any of those approaches. However, there are still some differences to know which might be useful to avoid runtime bugs.

For those who is only reading this quote, long story short, creating values with

literals are better than built-in constructors.

First, if you are wondering what these are.

Java Vs. JavaScript: Know the Difference

What a mess it could be to share the same name — especially if you are a programming language. Even if you are already over 20 years old, IT newbies periodically confuse you with your namesake. This happens all the time with Java and JavaScript, although they are not related at all! As someone on the internet said. They correlate in much the same way as a car and a carpet.

Why do these two languages have such similar names? How do they differ from each other, and what else do they have in common? This article will provide the answers to these questions.

Javascript let vs var: The Difference and Comparison

Javascript let, and var are both used for variable declaration. Before the ES6, JavaScript had only two types of scope:

1. Global Scope
2. Function Scope

Global Scope

Variables that are declared Globally (outside any function) have Global Scope.

var netflixFilm = "enola holms";

// code here can use netflixFilm

function detective() {
  // code here can also use netflixFilm
}

In this example, the variable is defined outside the function. So it is in the global scope.

You can access global variables anywhere in JavaScript programs.
