A countdown timer is a virtual clock that starts (or stops) counting down from a specific date to mark the start (or finish) of an event. They're commonly used on the landing page of an e-commerce website, under-construction websites, events pages, and a variety of other places. They're typically used...
Filtering through information is one of the most important tasks that we use automation/computers for! Computers and software wouldn't be nearly as useful if we had to sift through everything manually. By extension - filtering data for end-users is a common task, allowing users to narrow down the search...
Objects are used to store a collection of properties, each of which may be thought of as an association between a name (or key) and a value (a collection of key-value pairs). In this guide, we will explore many JavaScript methods on how to check if an object is empty....
Floating-points in JavaScript have an extremely high precision, and you don't always need this precision. Additionally - your user is even less likely to want it. More often than not - we'll want to "trim" floating-point numbers by setting a specific precision (such as, say, two decimal points)...
Floats and doubles represent floating-point numbers - numbers with decimal points. While this type is very useful for a wide variety of environments, depending on what they're used for, we sometimes want to round them to a whole number - closest whole integer, up or down. In this article, we...
As you aim to become a better JavaScript developer, it is expedient you understand some tricks and methods in JavaScript to save you from unnecessary hard-to-decode bugs in the future. Whenever users input string values through form fields, it is a good practice for you to remove the white spaces...
Programming has always included the definition of data, manipulation of data, and finally displaying data. Data can be represented as bits of information that we can alter in computer programs. Since memory locations aren't very human-readable, and change through time - we've started annotating variable data, with human-readable signifiers, which...
When writing JavaScript code, you may need to loop through JavaScript objects and enumerate their fields/values. Unfortunately, JavaScript objects are not iterable like arrays or strings, so we can't just loop an object using map(), forEach() or a for…of loop. Suppose we have an object which contains a...
