JavaScript's Comparative Conundrum: Deciphering the Truth Within (0
In the realm of JavaScript, a peculiar observation emerges: why does the expression (0
To unravel this mystery, we must delve into the sequence of operations performed by the expression:
- Parentheses First: Since there are no parentheses, this step is skipped.
- Exponentiation: There is no exponentiation, so we move on.
- Multiplication and Division: Again, these operators are absent.
- Addition and Subtraction: We have neither addition nor subtraction.
Comparison: Here's where the magic happens. The expression is evaluated as ((0
- First, 0 is compared to 5, resulting in true.
- The result of this comparison (true) is then compared to 3. However, JavaScript treats true as 1 and false as 0. So, 1 is compared to 3, producing true.
Hence, the entire expression (0
Similarly, (0
While this quirk may seem fascinating, its practical applications are limited. However, it serves as a testament to the importance of understanding order of operations in JavaScript programming.
