 # Debouncing
 
-Have you ever encountered this problem in your development: how to do a complex computation in a rolling event or to prevent the "secend accidental click" on a button?
+Have you ever encountered this problem in your development: how to do a complex computation in a rolling event or to prevent the "second accidental click" on a button?
 
 These requirements can be achieved with function debouncing. Especially for the first one, if complex computations are carried out in frequent event callbacks, there's a large chance that the page becomes laggy. It's better to combine multiple computations into a single one, and only operate at a precise point in time. Since there are many libraries that implement debouncing, we won't build our own here and will just take underscore's source code to explain debouncing.
