What is type coercion in JavaScript?

Understanding Type Coercion in JavaScript

Type coercion is a fundamental concept in JavaScript where the language automatically converts values from one type to another. This often happens when performing operations with mixed types.

Examples of Type Coercion

  • String to Number: When adding a number to a string, JavaScript tries to convert the string to a number.
  • Boolean Context: In contexts requiring a boolean value, such as conditional statements, JavaScript coerces values to true or false.

Explicit vs Implicit Coercion

  1. Implicit Coercion: This is done automatically by JavaScript.
  2. Explicit Coercion: Developers can manually convert values using functions like Number(), String(), and Boolean().

Understanding type coercion helps in avoiding unexpected results and bugs in your JavaScript code. Make sure to use explicit coercion when necessary to ensure code clarity and correctness.
