When writing JavaScript code, there may be instances when you need to delay the execution of a function. In this blog post, we will explore how to effectively use JavaScript timers such as setTimeout and setInterval to schedule function execution in the future. setTimeout() The setTimeout function allows you to delay the execution of a function by specifying a callback function and a time value representing the delay in milliseconds. Here’s an example:...
As a senior developer with a background in React, I recently embarked on a serious journey to learn SwiftUI, Apple’s modern UI framework for iOS, macOS, iPadOS, and watchOS. While I had dabbled with it in the past, I decided to give it another shot and dive deeper. My experience thus far has led me to some interesting observations. At first glance, SwiftUI bears a striking resemblance to React. From its declarative UIs to its embrace of immutability and data-driven UI changes, many of the core concepts introduced by React are present in SwiftUI....
In JavaScript, the propertyIsEnumerable() method is used to determine whether a specific property of an object is enumerable or not. This method is called on an object instance and accepts a string argument representing the name of the property. The propertyIsEnumerable() method returns true if the property exists in the object and is enumerable. On the other hand, if the property does not exist or is not enumerable, it returns false....
Learn the essentials of using the HTML iframe tag The HTML iframe tag enables us to embed content from other sites into our web pages. This tag creates a separate browsing context, ensuring that the content within the iframe does not interfere with the parent page. JavaScript and CSS elements are contained within the iframe and do not spill over to the parent page. Many websites utilize iframes for various purposes....
In JavaScript, the defineProperties() method of the Object object is used to create or configure multiple properties on an object. This method is versatile and allows for the creation and configuration of multiple properties in a single operation. Additionally, it returns the object after the properties have been defined. The defineProperties() method takes two arguments. The first argument is the object on which the properties will be created or configured. The second argument is an object that contains the desired properties....
In JavaScript, the includes() method can be used to determine whether a string contains a specific value as a substring. The method returns a boolean value, true if the string includes the specified value, and false otherwise. Here are a few examples to illustrate its usage: 'JavaScript'.includes('Script') // true 'JavaScript'.includes('script') // false 'JavaScript'.includes('JavaScript') // true 'JavaScript'.includes('aSc') // true 'JavaScript'.includes('C++') // false In the first example, 'JavaScript' contains the substring 'Script', so the includes() method returns true....
Introduction: Learn about the normalize() method in JavaScript, which is used to normalize strings based on Unicode normalization forms. This blog post will provide an overview of the different normalization forms and demonstrate the usage of the normalize() method. Understanding Unicode Normalization Forms: Unicode defines four main normalization forms - NFC, NFD, NFKC, and NFKD. These forms determine how equivalent characters are represented in Unicode. You can refer to the Wikipedia page on Unicode equivalence for a detailed explanation....
In this blog post, we will dive into the search() method of JavaScript strings. This method allows you to find the position of the first occurrence of a specific string within another string. The search() method returns the index of the start of the occurrence, or -1 if the string is not found. Let’s have a look at some examples: 'JavaScript'.search('Script') // returns 4 'JavaScript'.search('TypeScript') // returns -1 As you can see, in the first example, the search string ‘Script’ is found starting at index 4 within the string ‘JavaScript’....
In this blog post, we’ll dive into the details of the split() method in JavaScript. This method is used to truncate a string based on a specified pattern, returning an array of tokens as a result. Let’s start with an example to better understand how the split() method works. Consider the following code snippet: const phrase = 'I love my dog! Dogs are great'; const tokens = phrase.split('dog'); console.log(tokens); // ["I love my ", "!...
In this blog post, we will delve into the details of the indexOf() method in JavaScript. This method is used to determine the position of the first occurrence of a specified string within another string. If the desired string is not found, it returns -1. Let’s take a look at some examples to understand how this method works: 'JavaScript'.indexOf('Script') // Output: 4 'JavaScript'.indexOf('JavaScript') // Output: 0 'JavaScript'.indexOf('aSc') // Output: 3 'JavaScript'....
