Boolean

Overview

A Boolean is a data type that represents one of two values: true or false.

Key Characteristics

1. Basic Definition: A Boolean value is either true or false. These values are typically the result of comparison operations or logical expressions.

2. Type Conversion: Any value in JavaScript can be converted to a Boolean using the Boolean() function or double negation !!. Examples:

     Boolean(0); // false
     Boolean(1); // true
     

    
1. **Common Use Cases:**  
    **Conditionals:** Boolean values are essential in `if` statements to control the flow of a program\.
    ```js
      if (isAvailable) {
          console.log("The item is available!");
      }
      

**Logical Operators:** Boolean values work with operators like `&&`, `||`, and `!` for complex conditions\.
```js
  let result = isAvailable && isAffordable;
  

    
1. **Truthiness and Falsiness:**  
    Some values in JavaScript are inherently "truthy" \(treated as `true`\) or "falsy" \(treated as `false`\)\. **Falsy values** include: `false`, `0`, `""`, `null`, `undefined`, and `NaN`\.
