Learn the fundamentals of JavaScript type conversions Even though JavaScript is a loosely typed language, there may arise situations where you need to convert a value from one type to another. In JavaScript, we have primitive types like numbers, strings, booleans, and symbols, along with the object type. However, converting from or to null and undefined is not necessary. Here are some common conversion scenarios and techniques to achieve them:...
Python, a versatile programming language, provides a range of built-in types to handle different kinds of data. In this blog, we will explore the basics of Python data types and how to work with them effectively. String Strings are sequences of characters enclosed in quotes (’’ or “”). To check if a variable is of the string data type, you can use the type() function or the isinstance() function: name = "Roger" type(name) == str # True isinstance(name, str) # True Numbers Python supports two types of numbers: integers (int) and floating-point numbers (float)....

JavaScript is often said to be untyped, but that’s not entirely accurate. While it is true that JavaScript allows you to assign different types of values to variables, it does have types. In fact, JavaScript provides both primitive types and object types. Let’s take a closer look at the different types in JavaScript: Primitive types JavaScript has several primitive types: Number: All numbers in JavaScript are internally represented as floats. String: A sequence of characters enclosed in quotes....
In the world of Swift programming, numbers play a crucial role. They allow us to perform mathematical calculations and represent various data types. In this tutorial, we will explore the two main types of numbers in Swift: Int and Double. We will also discuss other numeric types and how to convert between them. Integers: Int An Int in Swift represents a whole number without a decimal point. It is used to store values such as counts, indices, or any other quantity that can be expressed as a whole number....
