Javascript is a programming language that can help to create dynamic pages and make it more interactive.
Javascript is described as prototype-based, high-level, multiparadigm, single-threaded, dynamic typing, and garbage-collected.

✔JavaScript is prototype-based

It means that JavaScript can create objects without defining its class

function Car (){
  this.color = 'red',
  this.wheels = 4
}

const firstCar = new Car();

✔JavaScript is high-level

JavaScript is a high-level language because it's easy to understand, and it doesn't have to manage resources at all or deal with hardware and operating system.

✔JavaScript is multiparadigm

JavaScript is very dynamic and it supports various types of programming styles such as:

1. Imperative programming paradigm

It's a paradigm that focuses on how the program should perform, through a set of instructions to follow, and the computer does what you want like:

• Object-oriented programming

• Procedural code
  

const arr = [1, 2, 3, 4, 5]
const result = []

for (let i=0; i < arr.length; i++){
   result.push(arr[i] * 3)
}

console.log(result)
// [3, 6, 9, 12, 15]

2. Declarative programming paradigm

It's a paradigm that focuses on what the program should accomplish without specifying the instructions on how to solve the problem like:

• Logic language

• Functional programming

• Domain-specific language
  

const arr= [1, 2, 3, 4, 5]
const result = arr.map(num => num * 3)

console.log(result) 
// [3, 6, 9, 12, 15]

✔JavaScript is single-threaded

It means that javascript can only execute one task, and each task must done and completed before the other task starts

function First() {
  console.log('First function');
}
function Second() {
  console.log('Second function');
}

First();
Second();
// First function
// Second function

✔JavaScript is dynamic typing

JavaScript interpreter assigns a type to a variable at a run time based on the value assigned to that variable

✔JavaScript is garbage-collected

The Garbage collector is an algorithm inside javascript engines, it automatically frees up memory by removing unused objects, which can help to prevent memory leaks.
