Welcome to your JavaScript fundamentals playlist! In this blog, we will delve into an essential aspect of JavaScript: type coercion & type conversion. As you continue your journey to become proficient in JavaScript, understanding how data types can be transformed and manipulated is crucial.
Type coercion and conversion enable you to handle different data types effectively, perform operations, and compare values. By the end of this blog, you will have a solid grasp of these concepts, empowering you to write more robust and reliable JavaScript code. So, let’s dive into the fascinating world of type coercion and conversion in JavaScript!
What is Type Coercion?
Type coercion refers to the automatic conversion of values from one data type to another, typically performed during operations or comparisons involving different data types. By using Type Coercion, JavaScript attempts to make the data types compatible to complete the operation or comparison.
Here are a few examples of type coercion:
Numeric to String Coercion:
var num = 42;
var str = "The answer is " + num; // Coercion: number to string
console.log(str); // Output: "The answer is 42"
