Class Component vs Functional Component: What's the Difference?
Introduction to Functional Components and Class Components It typically takes developers hundreds of lines of code to develop a single-page application that uses the traditional DOM structure. As a solution to this issue, a component-based approach gets used if the program requires some changes that are not easily updated. As
CSV Files in Python
Introduction The term "comma separated values" (or "csv") refers to a straightforward file format that uses certain formatting to arrange tabular data. It provides a standard format for data interchange and stores tabular data, such as from a spreadsheet or database, in plain text. The rows and columns of data
Displaying A to Z characters using a loop: C++ Program
Introduction In this article, we will be learning the approach to solve this problem of displaying characters from A to Z. Alphabets in lowercase and uppercase can be printed using two methods, first is using ASCII values and second is to directly print values from ‘A’ to ‘Z’ using loops.
Second Normal Form in DBMS
Introduction Have you heard something like normalization? Do you know about second normal forms or 2nf? If not, then don’t worry. Board Inifinity got your back. In this article, we will cover the 2nf or second normal form in normalization. We will discuss how this comes into the picture
Java Design Pattern: Factory Method
Introduction The construction of an object is discussed in this creational design pattern. According to the factory design pattern, establish an interface for producing objects (such as a Java interface or an abstract class) and allow the subclasses to choose which class to instantiate. A class may defer the instantiation
INDEX in SQL
Introduction The database search engine can use indexes, which are specialised lookup tables, to speed up data retrieval. An index is simply a pointer to information in a table. An index in a database resembles a book's back matter index quite a bit. For instance, if you want to find
slice() in Python
Introduction To extract a slice of the elements from the collection of elements, use the slice() method in Python. Python comes with two redundant slice routines. While the second method needs three arguments and returns a slice object, the first function only requires a single argument. You can retrieve a
filter() in Python
Introduction The filter() method in python filters the given collection or sequence with the help of a function which tests each element in the sequence holds true or not. Syntax Below is the syntax used for defining the filter function: filter(function, sequence) Parameters Parameters used by Python filter() function
Or Operator in Python
Introduction You can combine two Boolean expressions into one compound expression using the Boolean OR operator. It makes no difference which of the subexpressions is true for the compound expression to be true. If both subexpressions are false, the expression is incorrect. This is the underlying logic of the OR
Sets in Python
Introduction In math, a set is a group of things that are not necessarily in any specific order. With the additional constraints listed below, a Python set is identical to this mathematical definition. A set's characteristics: The built-in data structure in Python, known as a set, has the following three
