            Repeat: It is used to repeat the execution of a set of block multiple times.
                Logic  : It is used to add conditional blocks to the program.

            If-else: It is used to make decisions based on a condition. If the condition is true, then the if block
            is executed otherwise else block will be executed.

            BUILDING A MUSIC PLAYER

            Step  1   Open Makecode , click on 'New Project'. Write the name of project 'building a music
                      player', and click on 'Create'.

            Step  2   Click on 'Loops', and select 'repeat' block, drag it to the workspace and drop the 'repeat'
                      block to 'on start' block.












            Step  3   Change the value of '4' to '10' in the 'repeat' block.
            Step  4   In 'Music', select 'Play sound until done', it will appear on the workspace, and then drag
                      and drop the 'Play sound until done', block in the 'repeat' block.













            Step  5   Your code will be:
            Step  6   When you click on the 'Start the simulator' button, you will hear the music 10 times. The
                      loop repeats itself 10 times. The flow starts with 1 and with each iteration, it increments
                      the value by 1. Each time loop completes once iteration, and you will hear music once.
