What is JavaScript - Stackfindover - Blog

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.

Who invented JavaScript?

JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.

What is JavaScript?

JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.

Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.

JavaScript Hello World Program

In JavaScript, ‘document.write‘ is used to represent a string on a browser.

<script type="text/javascript">
	document.write("Hello World!");

How to comment JavaScript code?

  • For single line comment in JavaScript we have to use // (double slashes)
  • For multiple line comments we have to use / * – – * /
<script type="text/javascript">

//single line comment

/* document.write("Hello"); */

How to Convert Base 2 Binary Number String To integer In Python

In this pythonn tutorial we will learn about how to convert base 2 binary number string to integer in Python. Ever faced the challenge of converting a binary number string into an integer for smooth processing in your Python code? Python offers seamless solutions for transforming data types without a hitch, making it an ideal choice for developers worldwide.

In this article, we’ll delve into two popular methods to tackle binary string conversion: Python’s built-in int() function and the powerful bitstring library, part of the bit array package. Join us as we break down each approach, guiding you through the process of efficient typecasting in Python.

What Is A Base-2 Number String?

A binary number is expressed in the base-2 number system using only “0”s and “1”s. The zeros and ones are called the index of a binary number. They are also called “bits”.

A computer system only uses the binary system for computations. It is the way in which machine code is written. Circuit diagrams can be used to represent the working of binary systems.

Boolean algebra including “AND”, “OR” and “NOT” gates can be used to represent addition, subtraction, multiplications in the binary system.

We can easily convert a number that is an integer from the decimal system, that is the base-10 system to the binary system by dividing it with 2 and arranging the remainders in a bottom-to-top order.

From Decimal To Base 2 Conversion

Converting Decimal to Base-2 Numbers

A binary number can also be converted easily into a decimal number in mathematics.


Converting a Base-2 Number String to an Integer in Python

A string in python is something that is written between two quotation marks, for example, “this is a string”.

Hence, a base-2 number string is a binary number written between two quotation marks . For example-‘1010001’ is a base-2 number string.

Advantages of Explicit Typecasting in Python

In python, programmers can clearly define the conversion of one data type into another in their code. This is known as explicit typecasting in python.

Explicit typecasting is extremely useful. Unlike other programming languages, python has built-in functions that can perform explicit typecasting without having to write huge blocks of code for transforming one data type into another.

Explicit typecasting has many advantages. Some of them are:

  • It helps in converting lower data types into higher ones for ease of operations.
  • It prevents the loss of data when converting from one data type to another.
  • Functions like int() and str() are extremely helpful and hassle free to use.

Method 1: Converting Base-2 Number String to Integer Using int() Function

We can use the int() built-in function to convert a string literal into an integer in python. Let’s look at how we can implement this :

#converting a base-2 number string into an integer.
#taking an input for a number in the form of a string
inin=input("Enter a binary number= ")
#displaying the input
print("The given input is=",inin)
#converting using int()
#displaying the output
print("the number in the decimal system or as an integer is=",outout)

The output would be:

Enter a binary number= 10011
The given input is= 10011
the number in the decimal system or as an integer is= 19

Using The Int Function

Example: Converting Binary String with int() Function

Method 2: Converting Base-2 Number String to Integer Using BitString Library

The bitstring module helps in natural and easy creation of binary data. Binary data analysis and manipulation using bitstring comes in very handy along with the BitArray class.

Before we can use this module we have to install in it our system, run the following code in your command prompt:

pip install bitstring

Let’s see how we can implement this:

#converting a base-2 number string into an integer.
#importing required modules
from bitstring import BitArray
#taking an input for a number in the form of a string
inin=input("Enter a binary number= ")
#displaying the input
print("The given input is=",inin)
#converting using bitArray
#displaying the output
print("the number in the decimal system or as an integer is=",outout)

The output will be:

Enter a binary number= 0100111
The given input is= 0100111
the number in the decimal system or as an integer is= 39

Using The Bitstring Module

Example: Converting Binary String with Bitstring Module


Throughout this tutorial, we’ve explored the process of converting binary numbers to decimal integers in Python. With Python’s extensive library of built-in functions and modules, there’s no need for manual calculations. Explicit typecasting is a powerful feature that simplifies this conversion process. We have demonstrated two methods for converting base-2 number strings to integers: using the int() function and the bitstring module.
