Why Does '1' + 1 Equal '11' In JavaScript? Have you ever wondered why combining a string and a number in JavaScript results in unexpected output? In this informative video, we'll explain the key concept behind this behavior and how JavaScript handles different data types during operations. We'll start by discussing the nature of the plus operator in JavaScript and how it can serve two different functions: addition and string concatenation. We'll explain how JavaScript automatically converts data types in certain situations, a process known as type coercion, and how this affects the outcome of expressions involving strings and numbers. You'll learn why '1' plus 1 results in '11' instead of 2, and how to control this behavior if you want to perform numerical addition instead. We'll also share practical tips on explicitly converting data types to avoid surprises in your code, such as using the Number() function. Whether you're a beginner or looking to strengthen your understanding of JavaScript's type handling, this video will help you write clearer, more predictable code.
