15. Constants Constants are fixed values that do not change during execution time. Syntax: 1 2 const mybirthday; mybirthday = ‘03.08.1996’ ; Examples of constants

16. Primitive Data Types Numbers Strings Boolean TRUE FALSE Null Undefined

17. Reference Data Types - Objects An object is a standalone entity, with properties and type. Name Syntax: Age 1 let object1 = { }; Eye-colour

18. Reference Data Types - Arrays An array is a data structure that contains a list of elements. These elements are all of the same data type, such as an integer or string. 0 1 2 3 4 Syntax: 1 2 let arr[ ]; let arr = new Array( ) ;

19. Reference Data Types - Functions A function is a block of organized, reusable code that is used to perform a single, related action. name of the function enter parameters here Functions Syntax: 1 2 3 function greetings( ) { alert(‘ Hello everyone! ‘); } Predefined Functions User Defined Functions

20. Conditional Statements Conditional statement is a set of rules performed if a certain condition is met. It is like an ‘If-Then’ statement. (IF a condition is met, THEN an action is performed) If Statement Start False Syntax: Exit Condition 1 2 3 if(condition) { statement; } True If code End

21. Conditional Statements Conditional statement is a set of rules performed if a certain condition is met. It is like an ‘If-Then’ statement. (IF a condition is met, THEN an action is performed) Else If Statement Start Syntax: False Else if code Condition 1 2 3 4 5 6 if(condition) { statement a; } else (condition) { statement b; } True If code End

22. Loops Loops are used to repeat a specific block until some end condition is met. Start Loops Conditional Code True Condition while for do while False End loop

23. While Loop While the condition is true, the code within the loop is executed. While loop Start Syntax: False Condition 1 2 3 while(condition) { loop code; } True Conditional Code End

24. Do While Loop This loop will first execute the code, then check the condition and while the condition holds true, execute repeatedly. Do while loop Start Syntax: Conditional Code 1 2 3 4 do { loop code; } while(condition); True Condition False End

25. For Loop Repeatedly executes the loop code while a given condition is TRUE. It tests the condition before executing the loop body. Start For loop If no more items Item from sequence Syntax: Next item from sequence 1 2 3 for(begin; condition; step) { loop code; } Execute Statement (s) End

26. Switch Case Start The switch statement is used to perform different actions based on different conditions. Switch expression Code block 1 break; Syntax: Case 1 1 2 3 4 5 6 7 8 9 10 switch(expression) { case 1 : code block 1 break; case 2 : code block 2 break; default : code block 3 } False Code block 2 break; Case 2 False Default Default statement End
