Explanation:
The + and - unary operators convert the strings "5" and "2" to numbers. Then, 5 - -2 evaluates to 7.

JavaScript is a powerful and versatile programming language, with operators forming one of its most fundamental components. Among these operators, unary operators are often overlooked but are essential for performing concise operations on single operands. In this blog, we will dive into the world of unary operators in JavaScript, exploring their functionality and use cases.

What Are Unary Operators?

A unary operator is an operator that operates on a single operand to perform a specific task. Unlike binary operators that require two operands (e.g., +, -, *, /), unary operators work with just one. These operators can be used to modify values, perform type conversion, or return specific results based on the operand provided.

Here’s a list of unary operators in JavaScript:

1. + (Unary Plus)
2. - (Unary Negation)
3. ++ (Increment)
4. -- (Decrement)
5. ! (Logical NOT)
6. typeof
7. delete
8. void
9. ~ (Bitwise NOT)
