Data Types and Variables
In this article I'll be answering a few questions about Data types and Variables in Javascript. Source to the article containing the questions can be found at Turing.
The five primitive data types in Javascript are: Boolean Undefined Null Number String
Variables are places we store data. There are needed in every type of program conceivable. As a program is running, it needs to hold information in it's memory to perform all sorts of operations. Variables are needed to temporarily store small and large pieces of data. Example:
let girl = 'ADA'
An example of a string concatenation is
let firstName = 'Dioka'
let lastName = 'Ejionueme'
let Name = firstName + " " + lastName;
console.log(Name)
Using template literals:
let firstName = 'Dioka'
let lastName = 'Ejionueme'
let Name = `${firstName} ${lastName}`;
console.log(Name)
Question
Considering Javascript is a loosely typed language which gives a lot of flexibility to what can be
done, what are the negative effects of that? Do they outweigh the necessity of 'flexibility' it
offers?
