while Loop:
- A control structure that repeatedly executes a block of code as long as a specified condition is true.
do...while Loop:
- A control structure that executes a block of code once before checking the condition, ensuring the code runs at least once.
Infinite Loop:
- A loop that never terminates because the exit condition is never met, often resulting in program crashes or unresponsiveness.
Break Statement:
- Exits the loop immediately, regardless of whether the loop condition is still true.
Continue Statement:
- Skips the current iteration of the loop and proceeds to the next iteration.
Loop Condition:
- An expression that determines whether the loop will continue to execute or terminate.
Precondition vs. Postcondition:
- Precondition (while): Condition is checked before the loop body executes.
- Postcondition (do...while): Condition is checked after the loop body executes.

Early JavaScript Development (1995): Introduced both while and do...while loops as part of the core language, enabling developers to handle repetitive tasks efficiently.
Influence from Other Languages: The syntax and functionality of these loops were heavily influenced by C and other programming languages, ensuring consistency and ease of learning for developers transitioning to JavaScript.
Modern Enhancements: While the fundamental behavior of while and do...while loops remains unchanged, modern JavaScript practices emphasize writing clean and efficient loop conditions to prevent infinite loops and enhance code readability.

Guaranteed Execution:
- The do...while loop ensures that the loop body runs at least once, making it ideal for scenarios where the initial execution is required before any condition checks.
Flexibility in Conditions:
- while loops offer more flexibility in how and when conditions are evaluated, allowing for complex and dynamic loop termination conditions.
Real-World Applications:
- do...while loops are commonly used in scenarios like user input validation, where the prompt needs to run at least once.
Preventing Infinite Loops:
- Properly managing loop conditions and using statements like break can prevent accidental infinite loops, which are a common source of bugs in programming.
Historical Usage:
- In the early days of web development, while and do...while loops were frequently used to handle animations and interactive elements before the advent of more advanced frameworks and libraries.
