Learn Synchronous and Asynchronous JavaScript

Synchronous In synchronous programming, tasks are done one after another in order. Each line of code waits for the previous one to finish before moving to the next. This means the program runs step by step in a clear and predictable way. console . log ( " Start " ); console . log ( " Task 1 " ); console . log ( " Task 2 " ); console . log ( " End " ); In this example, "Start" is printed first, followed by "Task 1", then "Task 2", and finally "End". Each line runs only after the previous one has finished. This shows that the code executes in a fixed order, step by step, without skipping any task. Asynchronous In asynchronous programming, tasks can run independently without waiting for previous tasks to complete. While one task is in progress, other tasks can continue running. This improves performance and makes applications faster and smoother. console . log ( " Start " ); setTimeout ( function () { console . log ( " Task 1 " ); }, 2000 ); console . log ( " End " ); Output : Start End T
