In TypeScript, we need to define the types for every variable and object as it is a type of strict language and also contains conditional types. From the word conditional type, we can predict that we need to choose a variable based on a particular condition. Yes, you heard right. As we use an if-else statement to execute the particular code block based on a certain condition, we can also choose a type of variable based on a certain condition. In this tutorial, we will learn to create condition types in TypeScript. Syntax Users can follow the syntax below to ... Read More
The string and number are both primitive data types in TypeScript. Sometimes, we get the number in the string format, and we need to convert the string values to the number to perform mathematical operations on the value. If we perform the mathematical operation on the string values, it gives weird results. For example, adding another number value to the string of numbers appends the number to the string rather than adding. We will learn to convert strings to numeric values using various methods and approaches in TypeScript. So, we require to convert the string to a number in TypeScript. ... Read More
The longest side of a right-angled triangle and the side that faces away from the right angle is known as the Hypotenuse. The Pythagorean theorem explains that the Hypotenuse's square equals the sum of the squares of the other two sides. We can be used to determine it using this theorem. The formula representation for this theorem is c2 = a2 + b2, where c means the Hypotenuse and a and b are the triangle's two sides. When the lengths of the other two sides of a triangle are known, the Pythagorean theorem quickly determines the value of the Hypotenuse. ... Read More
What is Duck Typing? First, we will know what Duck Typing is. According to programmers, the circumstance where an object's type is decided by its behaviour, like methods and attributes, rather than its class is known as "duck typing". Duck Typing in TypeScript The usage of interfaces in TypeScript makes duck typing possible. Where interface means the set of methods and characteristics an object must have to fall under that type are described. For example, if an interface defines the function, any object with the method called "myFunc()" may be treated as belonging to a specific kind, regardless of ... Read More
In React with TypeScript, you can use conditional rendering to choose what to render based on a condition. This is useful when displaying different content or components based on specific criteria. There are a few different ways to implement conditional rendering in React with TypeScript. One way is to use the conditional operator (also known as the ternary operator). This operator takes a condition and returns one value if the condition is true and another if the condition is false. You can also use the && operator to render a component based on a condition conditionally. This operator evaluates to ... Read More
In TypeScript, to access an element, or we can say HTML components, we use the Document Object Model (DOM). The DOM defines an HTML and XML programming interface that visualizes a document's structure as a tree of nodes. A paragraph, a button, a div, a heading, etc., are just a few examples of the document elements each node in the tree represents. The document object in TypeScript serves as the doorway to the DOM. This means we can easily access the elements of the DOM using TypeScript. There are several ways to access elements, those are − Using the ... Read More
RAID or Redundant Array of Independent Disk is a set of disk organization techniques developed to increase the reliability and performance of a system. There are various types of RAID techniques such as RAID 0, RAID 1, RAID 2, … RAID 5. Read this article to learn more about RAID 0 and RAID 1 and how they are different from each other. What is RAID 0? RAID 0 stands for Redundant Array of Independent Disk level 0. There is no redundant data stored here, so performance is very good. But the failure of any disk in the array results in loss of data. In RAID 0, ... Read More
The task of arranging the elements of an array in a particular order is referred to as sorting. The sorting of an array or a list is mainly done to make the searching easier. There are several types of sorting algorithms, but in this article, we will concentrate on quick sort and merge sort. Both quick sort and merge sort algorithms are based on the divide-and-conquer sorting algorithms, hence they work almost in a similar way. Read this article to learn more about quick sort and merge sort and how these sorting techniques are different from each other. What is ... Read More
In Operating Systems, Preemptive Scheduling is a type of CPU scheduling method in which the CPU is allocated for a limited time to a given process. In contrast, Non-Preemptive Scheduling is the scheduling technique in which the CPU is allocated to a process and hold by it till the process gets terminated. Read this article to learn more about Preemptive and Non-Preemptive Scheduling in Operating System and how they are different from each other. What is Preemptive Scheduling? Preemptive Scheduling is a type of CPU scheduling in which the resources (CPU Cycle) have been allocated to a process for a ... Read More
Testing is an important stage in the process of delivery of any software product. It not only validates the quality of a software product but also provides an opportunity to the developer to improve its product. There are various types of software testing which are carried out to test different aspects of a software product. In this article, we will concentrate our focus on Performance Testing and Stress Testing. The most basic difference between these two types of testing is that performance testing is performed to check the performance of a software, website, network, etc. for different load conditions, while ...
