Introduction When it comes to creating cost functions, catalog information is a crucial piece of data that can be used to optimize the performance of a model. In this article, we will explore how catalog information can be used in cost functions, the different types of catalog information available, and how to implement this in your code. What is Catalog Information? Catalog information refers to data that describes the products or items that are being sold by a company. This information can include things like product names, descriptions, pricing, and images. This data is often stored in a database and ... Read More
In this TypeScript tutorial, we will learn to convert the string to uppercase. We need to convert every single alphabetic character to uppercase to convert the whole string uppercase by keeping the numbers and special characters as it is. As a beginner TypeScript programmer, maybe a question can arise in your mind what is the need to convert the string to uppercase? Here is the very straightforward answer. Have you ever used the search bar of any website, which shows different results when you search? If yes, search the uppercase and normal strings, which will return the search result. It ... Read More
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 ...

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 More
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 More
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
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
Introduction Ulimit is a Unix/Linux utility that is used to set resource limits for processes running on the system. These limits can help prevent a single process from consuming too many resources, such as CPU or memory, and potentially impacting the overall performance of the system. To see the ulimit on your Linux machine, use the below command. $ ulimit –a Output real-time non-blocking time (microseconds, -R) unlimited core file size (blocks, -c) 0 data seg size ... Read More
