Example
Here is a practical example demonstrating JS Timing Functions:
Tips & Best Practices
- Use
constby default,letwhen you need to reassign - Use strict equality (
===) instead of loose equality (==) - Handle errors with try/catch blocks for robust code
- Use template literals instead of string concatenation
