Synchronous validation occurs during the execution of a program, blocking further actions until validation is complete. It’s best used when immediate feedback is necessary, such as form input validations where user mistakes can be corrected on-the-spot.
Example:
function validateInput(input) {
if (input === '') throw new Error('Invalid Input');
}
try {
validateInput('');
} catch (error) {
console.error(error);
}
Asynchronous validation, however, doesn’t block program execution and allows other operations to continue while validation is in progress. This is ideal for server-side validations or tasks that may take time, like checking database records.
