# JavaScript Switch Statement

● The JavaScript Switch Statement

Use the switch statement to select one of many blocks of code to be executed.

● The break keyword

When JavaScript reaches a break keyword, it breaks out of the switch block.
this will stop the execution of more code and case testing inside the block.
When a match is found, and the job is done, it's time for a break. There is no need for more testing. It is not necessary to break the last case in a switch block. The block breaks there anyway.

● The default keyword

The default keyword specifies the code to run if there is no case match.

The default case does not have to be the last case in a switch block.

● Common Code Blocks

Sometimes programmer will want different switch cases to use the same code.
In this example case 4 and 5 share the same code block, and 0 and 6 share another code block.
