Working with Arrays Arrays are fundamental data structures in JavaScript, and they offer several powerful methods to manipulate and transform data. Let's explore some ... Read More
ASCII (American Standard Code for Information Interchange), is a character encoding system that represents every character as a unique 7-bit binary code i.e. ASCII values are a numerical representation of characters. The ASCII values are 7-bit binary codes that range from 0 to 127. For Example, the ASCII code for a space character is 32, and for digit ‘1’ ASCII code is 49 and similarly ASCII codes are assigned to each character which is represented in an ASCII table. In Python, the ASCII code of a character can be computed using a predefined function ord(), which takes a character as ... Read More
