# Introduction

In this post, I will explain why declarative code is better than imperative code.

Then I will list some techniques to convert imperative JavaScript to a declarative one in common situations, defining key terms along the way.

# Why declarative ?

First, let’s define what declarative and imperative mean.

Declarative code is one that highlights the intent of what it’s doing.

It favors the “what” over the “how”.

In other words, the exact implementations actually doing the work (aka the “how”) are hidden in order to convey what that work actually is (aka the “what”).

At the opposite, imperative code is one that favors the “how” over the “what”.

Let’s see an example:

The snippet below perform two things: it computes the square of `x`, then check if the result is even or not.

``````// imperative way

const x = 5;

const xSquared = x * x;

let isEven;

if (xSquared % 2 === 0) {
isEven = true;
} else {
isEven = false;
}
view raw
block1.js hosted with ❤ by GitHub
``````

Here, we can see that we finally get `isEven` after several steps that we must follow in order.

These steps describe “how” we arrive to know if the square of `x` is even, but that’s not obvious.

If you take a non-programmer and show him this, he might have a hard time deciphering it.

Now let’s see another snippet where I introduce a magic `isSquareEven` function that performs the two same things than the previous one.

## [ Professor JavaScript ]: Introduction

Professor JavaScript is a JavaScript online learning courses YouTube Channel. Students can learn how to develop codes with JavaScript from basic to advanced levels through the online courses in this YouTube channel.

It is additional online learning material for Professor JavaScript YouTube channel, Part 1: Introduction.

## Introduction

A lot of people often confuse the differences between JavaScript and Java programming languages. Both programming languages are different completely in concept and design.

JavaScript is a high-level programming language which was invented by Brendan Eich in the year 1995. It became an ECMA standard in 1997. ECMA-262 is the official name of the standard. ECMAScript is the official name of the language. JavaScript is mostly coded on HTML files. Almost all web browsers have built-in JavaScript Engine that executes JavaScript codes on HTML files. “JavaScript” is a trademark of Oracle Corporation in the United States.

Java programming language is a high level, object-oriented, and cross platforms ( Java codes can run on many different operating system software such as Microsoft Windows, iOS, Linux, etc. ) programming language. It was invented by James Gosling at Sun Microsystem company in the year 1995. Java can be used to develop desktop software, cloud-based software, and mobile apps.

“Java is to JavaScript as ham is to hamster.”
