How to create a queue in TypeScript using an array?
We will learn to create a queue from scratch using the array in TypeScript in this tutorial. The Queue is a data structure allowing users to add elements from the end and remove them from the start. It means it works based on the FIFO concept, meaning first in, first out. Also, we can’t remove the element randomly from the queue like an array. We can only remove elements from the first index and add them to the last empty index. Here, we will use some concepts of object-oriented programming language to create a queue using an array. Methods of ...
Read MoreTackling recursion (not just) in Typescript
Recursion is a fundamental programming concept that refers to a function calling itself. It can be a powerful tool for solving problems, but it can also be a source of confusion and frustration, especially for beginners. In this tutorial, we'll explore how to use recursion effectively in TypeScript, a popular superset of JavaScript that adds optional static typing and other features. One important thing to keep in mind when working with recursion is to define a base case, which is a condition that stops the function from calling itself again. Without a base case, the function will keep calling itself ...
Read MoreHow to create function overload in TypeScript?
The function or method overloading allows developers to create multiple functions with the same name. Every function contains the same number of parameters but different data types. Also, the return type of the overloaded function can vary. Function overloading is the concept of object-oriented programming. Also, TypeScript supports OOPS, so we can easily implement function overloading in TypeScript. Furthermore, function overloading provides code reusability and helps developers to increase code readability. Let’s understand the use of function overloading via real-life examples. For example, you have created a function that takes a string as a parameter and returns the length of ...
Read MoreHow to use interface with class in TypeScript?
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 MoreHow to use delete Operator in TypeScript?
Have you ever tried to delete the object properties in TypeScript? Then you definitely came across the ‘delete’ operator. In TypeScript, the delete operator only allows deleting the undefined, optional, or any object properties. Also, it returns the boolean values according to whether it deletes the property or not. Below, we will understand the different use cases of the delete operator in TypeScript via different examples. Using the Delete Operator to Delete the Object Properties The main use of the delete operator is to delete the optional properties of an object. We can use the delete keyword as an operator ...
Read MoreHow to round the numbers in TypeScript?
In this tutorial, we will learn to round numbers in TypeScript. In TypeScript, the number data types can contain number values with decimal parts, and sometimes, we require to remove decimal part by rounding the number value. For example, if you want to show the progress of something in the application, and you are getting the decimal value of the progress, but you want to show the integer values only, then it is required to round the numbers. Here, we will learn 3 to 4 different methods to round the numbers. Using The Math.round() Method to Round a Number In ...
Read MoreWhat is the use of this keyword in TypeScript?
The “this” keyword is one of the most used keywords in TypeScript. For beginner TypeScript programmers, it’s complex to understand how this keyword works, but they will learn by the end of this tutorial. In this tutorial, we will learn to use this keyword in TypeScript. Syntax Users can follow the syntax below to use this keyword generally. Users can observe how we can access the variable or invoke the method using this keyword. this.var_name; this.method_name(); console.log(this.var_name); In TypeScript, this keyword refers to the global object if it’s not used inside any class or method. Even if we use ...
Read MoreHow to encode and decode URl in typescript?
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 ...
Read MoreFor-In Statement with Object in TypeScript
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 MoreExplain the different ready states of a request in AJAX
AJAX stands for Asynchronous JavaScript and XML. It is a set of web development techniques to create interactive web applications. AJAX allows a web page to communicate with a server without reloading the page. Ready states are an important part of working with AJAX requests. The ready state of a request indicates the request’s status to the server and allows the client to track the progress of the request. In the below, we detailed the different ready states of AJAX. UNSENT STATE (0) This is the first ready state of the AJAX. It is denoted by the integer 0. When ...
