The URI stands for the uniform resource identifier. The URL is one of the most common URIS. We use the URL (uniform resource locator) to find the web page located on the internet. The web pages also contain resources. In simple terms, URI is a string containing some characters, and we can identify the physical and logical resources on the web using the URI. The URL is a subset of the URI, which stores the document address on the web. Reasons to Encode URI The first question that arises in your mind after reading this tutorial's title is why we ...

The object contains the key-value pairs of its properties, or it can be an instance of the class in TypeScript. The class and its objects are the base of object-oriented programming. So, without an object, OOPS doesn’t exist. Mainly, objects are used to invoke the non-static methods of the class. There are multiple ways to define the objects in TypeScript. We will learn all ways to define objects one by one below. Use The Object Literal Notation to Create Objects The object-literal notation means we can create the object using the two curly braces. By comma separation, we need to ... Read More

In TypeScript, we can declare the function using the function keyword. It is a block of code that performs some operation, and we can reuse the function code by invoking the function. There are two types of functions. One is a named function, and another is an anonymous function. The name function means we can identify it using the unique identifier, and the identifier doesn’t exist for the anonymous functions. We will talk about anonymous functions in depth in this tutorial. As the word ‘anonymous function’ states, it means a function defined without any name or identifier. We can simply ... Read More

Introduction to Abstraction We wanted readers to get familiar with abstract classes and the requirements of abstract classes before implementing them. The abstraction means hiding. It is used to hide the lower-level code implementation from users and some developers. Furthermore, it is used to show only the required information about the method rather than showing the whole complex implementation of methods. Create Abstract Classes We can use the abstract keyword to define the abstract classes or methods. The abstract classes can contain the normal and abstract types of methods. In the abstract class, we need to implement the functional or ... Read More

In TypeScript, an object contains the properties and their values. We can use the for-in loop statement to iterate through every property of the objects and get its value. This tutorial will teach us to iterate through the object key-value pairs via different examples. Also, we will learn what kind of error we can get while iterating through the object properties and how to fix it quickly. Syntax Users can follow the syntax below to iterate through the iterable object properties using the for-in loop statement. For (var_name in object){ Statements or block to execute; } ... Read More

In TypeScript, classes are the template that defines the variables and methods. We can use class templates to create objects, which means the class is the reusable component in object-oriented programming, and we can reuse it by creating its object. We can use the ‘interface’ keyword to define the interfaces in TypeScript. The interface contains the class structure. The interface is similar to abstract classes we define in other programming languages, such as Java and C++. It contains only the declaration of variables with their type and method with its return type and parameter types. Classes define the interface's methods ... Read More

Introduction In machine learning, the data features are one of the parameters which affect the model's performance most. The data's features or variables should be informative and good enough to feed it to the machine learning algorithm, as it is noted that the model can perform best if even less amount of data is provided of good quality. The traditional machine learning algorithm performs better as it is fed with more data. Still, after some value or the quantity of the data, the model's performance becomes constant and does not increase. This is the point where the selection of the ... Read More

Introduction In machine learning, the data and the knowledge about its behavior is an essential things that one should have while working with any kind of data. In machine learning, it is impossible to have the same data with the same parameters and behavior, so it is essential to conduct some pre-training stages meaning that it is necessary to have some knowledge of the data before training the model. The correlations are something every data scientist or data analyst wants to know about the data as it reveals essential information about the data, which could help one perform feature engineering ...

In this article, we will learn about the ** operator in Python. Double Star (**) is an Arithmetic Operator (like +, -, *, **, /, //, %) in Python. Power Operator is another name for it. What Order/Precedence Do Arithmetic Operators Take? The rules for both Arithmetic operators and Mathematical operators are same, which are as follows: exponential is run first, followed by multiplication and division, and then addition and subtraction. Following are the priority orders of arithmetic operators used in decreasing mode − () >> ** >> * >> / >> // >> % >> + >> - ... Read More
