Documentation	Comment		-- This is a comment	// This is a comment	// This is a comment	# This is a comment	# This is a comment	' This is a comment
Collection	Array			struct myInfo { int myNum; string myName;};
Collection	Structure (aka struct)	A way to group several related variables into one place.		if a > b
Comparison	Greater Than			if a > b		if a > b		If a > b Then
Comparison	Less Than			if a < b		if a < b		If a < b Then
Comparison	Equal To			if a == b
Comparison	Not Equal To			if a != b		if a != b		If a <> b Then
Computation	Addition			a = b + c				a = b + c
Computation	Division			a = b / c				a = b / c
Computation	Multiplication			a = b * c				a = b * c
Computation	Subtraction			a = b - c				a = b - c
Conditional	Case			switch(expression {case x: // code break; case y: // code break; default:// code }		case fruit when 'Apple' result = '1 a day' when 'Pear' result = '1 a week' else result = 'unknown' end		Select Case(Fruit) Case "Apple" Result = "1 a day" Case "Pear" Result = "1 a week" Case Else Result = "Unknown" End Select
Conditional	If - And - Then							If a = 1 and b = 2 Then
Conditional	If - Or - Then							If a = 1 of b = 1 Then
Conditional	If - Then - Else			if (time < 18) {  cout << "Good day.";} else {  cout << "Good evening.";}		if result == 'pass' puts 'Pass' elsif result == 'fail' #Note how elsif is spelled puts 'Fail' else puts 'Other' end		If a = b Then print "a equals b" ElseIf a = c Then print "a equals c" Else print "a does not equal b" End If
Conditional	Ternary	Short-hand if else statement.		result = (time < 18) ? "Good day." : "Good evening.";		var_is_greater_than_three = (var > 3 ? true : false)
Date	Addition							EstHours = DateAdd("d",Days,Today)
Date	Difference							EstHours = DateDiff("h",FirstDate, SecondDate)
Dialog			display dialog "Hello World"		var app = Application.currentApplication(); app.includeStandardAdditions = true; app.displayAlert("This is a message");
IO	Input			cin >> x; // Get user input
IO	Output			cout << "Hello World!";		puts "Hello World"	echo "Hello World"
IO	Serial Monitor or Terminal			Serial.begin(115200);Serial.println("Hello\nWorld");"		puts "Hello World"
Load URL			open location "https://gregpaskal.com/"
Logical	And	Returns true if both are true		if a = 1 && b = 2
Logical	Or	Returns true if one or the other are true		if a = 1 || b = 2
Logical	Not	Returns true if results are false		if a != 1
Loop	Do			do {  cout << i;  i++;}while (i < 5);				i = 0 Do Print "Hello" i = i + 1 If i = "" Then Exit Do End If Loop until i > 5
Loop	For			for (int i = 0; i < 5; i++) {  cout << i;}		for i in 1..10 puts i end		For i = 1 to 10 print i Next
Loop	While			while (i < 5) {  cout << i;  i++;}
Speak
String	Concatanation	Joining multiple strings together	set theDialogText to "The current date and time is " & (current date) & "."	fullName = firstName + lastName;		filespec = filepath + filename		Result = "Age = " & MyAge
String	Interpolation		(Not possible in AppleScript)			Result = "Hello #{first_name}"
String	Length	Get the length of a string		theLen = txt.length();
String	New line	Start a new line		\n
Type	Bool			bool myBoolean = true;
Type	Double			double myLargeNum = 556.9923234;
Type	Character	Store a single character		char myLetter = 'D';
Type	Float			float myFloatNum = 5.99;
Type	Integer			int myNum = 15;				a = Int(12.34)
Type	String			string myText = "Hello";
Time	Delay	Waiting for a designated delay		delay(250);		sleep(1)
Variable	Class	Shared by all instances of a class				@@URL = 'www.mysite.com'
Variable	Constant	Value to stay the same for the duration of the code execution. Changing value will generate warning.		const float PI = 3.14;		URL = 'www.mysite.com'
Variable	Global	Shared across the entire program				$URL = 'www.mysite.com'
Variable	Instance	Belongs to the object itself				@URL = 'www.mysite.com'
Variable	Local	Only accessible from the block it's initialize from	set myName to "Bob Smith"			a = 1	ma_name="Bob Smith"	a = 1
Variable	Pre-defined	__FILE__ (Current File) __dir__ (Current Directory) __LINE__ (Current Line)				MyFile = __FILE__
