In JavaScript, the values() method of the Object object is a powerful tool that allows you to easily fetch all the property values of an object. This method returns an array containing all the values of the object’s own properties. Usage: To better understand how the values() method works, let’s look at a couple of examples: Example 1: Retrieving Values from an Object const person = { name: 'Fred', age: 87 }; Object....
Voltage is a fundamental concept in electronics that refers to the electric potential that allows electrons to flow from an area of higher voltage to an area of lower voltage. It is measured in volts (V). The higher the voltage, the greater the flow of electrons in a circuit, which is known as current. To better understand voltage, let’s consider a simple example. Imagine a circuit with an LED light. If you power this circuit with a 1....
Vue.js provides a powerful feature called watchers, which allows you to monitor changes in specific properties of a component’s data and take action accordingly. This blog post will explain how watchers work and provide examples to illustrate their usage. What are Vue.js Watchers? A watcher in Vue.js is a special feature that enables you to observe changes in a specific property of a component’s state. It allows you to define a function that will be executed whenever the value of the watched property changes....
When working with React, you may come across the term “Unidirectional Data Flow.” But what exactly does it mean? Unidirectional Data Flow is not a concept exclusive to React, but as a JavaScript developer, this may be your first encounter with it. In general, Unidirectional Data Flow refers to the idea that data has only one way to be transferred within an application. In the context of React, Unidirectional Data Flow takes on the following meaning:...
Learn how to properly uninstall an npm Node package, whether it is installed locally or globally. To uninstall a package that was previously installed locally in the node_modules folder, you can run the following command from the project’s root folder: npm uninstall <package-name> This will not only remove the package from the node_modules folder but also remove its reference from the package.json file. If the package was installed as a development dependency and listed in the devDependencies section of the package....
A shell is a command interpreter that provides users with a text-based interface to interact with the operating system. It allows you to execute operations using commands, provides advanced features like scripting, and offers optimized ways to perform tasks compared to a Graphical User Interface (GUI). Unix shells, commonly found on Linux and macOS computers, come in different variations. The most prevalent ones include Bash, Csh, Zsh, and Fish. These shells have evolved from the original Bourne Shell, commonly known as sh, developed by Steve Bourne....
In this tutorial, we will learn how to update a checkbox value in a Notion database using the Notion API. Each entry in the database is treated as a page, and we will assume that you have the entry stored in a variable called page with its unique ID available as page.id. Additionally, we will assume that you have already initialized the Notion client. To begin, make sure you have imported the required Client module from '@notionhq/client' and properly initialized the Notion client by providing your authentication token stored in the process....
When it comes to being on the road in a van or motorhome, having enough electrical power is crucial. Whether you’re off-grid or away from a power source, the need to recharge devices and run appliances throughout the day is constant. This is where solar panels come in handy, providing a sustainable source of energy. However, solar panels can lose efficiency over time, which is why I decided to upgrade the existing 100W solar panel on my van that came with it when I bought it....
I recently discovered that you can use a GoPro Hero 7 White as a remote webcam using a Python package called GoPro API for Python. This package can be found on GitHub at https://github.com/konradit/gopro-py-api. To get started, you’ll need to install the package using the command pip3 install goprocam and enable the WiFi connection on your GoPro. Enabling the WiFi connection will activate a WiFi network created by the GoPro. Connect your computer to this network....
As your C program grows larger, it becomes essential to organize it into multiple files. This is where C header files come into the picture. A header file in C is a separate file that contains declarations instead of function implementations. It looks like a regular C file but has a .h extension instead of .c. When you include a header file, you can access the declarations written in that file....
