INTRODUCTION
Pattern is a series of repeated occurrences in some sort of a sequence. In the same way,
there is a pattern in code too. When you are programming, there are times when you want
the computer to repeat certain lines of code in sequence. If there is a block of code that you
need to repeat in different scenarios, you can use a function. Functions are blocks of code
that can be used repeatedly for similar scenarios. A real life analogy to a function would be
a function.
WHAT EXACTLY ARE FUNCTIONS?
Function is a block of code which is executed only when it is called and performs a single
specified action.
Experiential Learning
Coding Task 01
Calling a function which has no parameters
To perform the task, follow these steps:
Step 1: Open MakeCode Arcade and create a new project, ‘Function with no parameter’.
Click on ‘Create’.
Step 2: Click on ‘Advanced’, select ‘Functions’, and click on ‘Make
a Function...’. Click on ‘Done’. The function will appear.
Step 3: You can rename the function, by clicking on
‘doSomething’, in this case we have renamed the
function as ‘Touchcode-7’.
