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....

Subtracting two matrices in NumPy is a pretty common task to perform. The most straightforward way to subtract two matrices in NumPy is by using the - operator, which is the simplification of the np.subtract() method - NumPy specific method designed for subtracting arrays and other array-like objects such...

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...
Converting an object into a savable state (such as a byte stream, textual representation, etc) is called serialization, whereas deserialization converts data from the aforementioned format back to an object. A serialized format retains all the information required to reconstruct an object in memory, in the same state as it...

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...
Textual data is typically stored through sequences of characters - strings. These sequences, are ultimately, arrays, and converting between the two structures typically is both simple and intuitive. Whether you're breaking a word down into its characters, or a sentence into words - splitting a string into an array isn't...
