It ensures that the execution order of the code aligns with the expected sequence.JavaScript's Single ThreadJavaScript is known for being a single-threaded language, meaning it executes one task at a time. This can lead to a significant issue: if a thread is blocked, the entire program becomes unresponsive. To address this, JavaScript introduced the event loop mechanism. This mechanism allows JavaScript to handle asynchronous operations while executing tasks, thus improvi...
