Also, there should not be any other statement in between a label name and associated loop. Note − Line breaks are not allowed between the ‘continue’ or ‘break’ statement and its label name. We will see two different examples to understand how to use labels with break and continue. A label is simply an identifier followed by a colon (:) that is applied to a statement or a block of code. Starting from JavaScript 1.2, a label can be used with break and continue to control the flow more precisely. Notice how the continue statement is used to skip printing when the index held in variable x reaches 5 − This example illustrates the use of a continue statement with a while loop. When a continue statement is encountered, the program flow moves to the loop check expression immediately and if the condition remains true, then it starts the next iteration, otherwise the control comes out of the loop. The continue statement tells the interpreter to immediately start the next iteration of the loop and skip the remaining code block. We already have seen the usage of break statement inside a switch statement. Set the variable to different value and then try.
