| // Line 1 is a variable declaration, creating the count variable with an initial value of 0 | ||
| // Describe what line 3 is doing, in particular focus on what = is doing | ||
| // Line 3 is a statement that is reassigning the value of count, to add 1 to the initial declaration which was 0. |

Operation like count = count + 1 is very common in programming, and there is a programming term describing such operation.
Can you find out what one-word programming term describes the operation on line 3?
| // It will help to think about the order in which expressions are evaluated | ||
| // Try logging the value of num and running the program several times to build an idea of what the program is doing | ||

| // Here, Math.rondom creates a random number which is greater than or equals to 0 and less than 1. |

We can also use the concise and precise interval notation to describe a range of values.
[,]=> inclusion(,)=> exclusion
For example, we can say, "Math.random() returns a random number in [0, 1)"
| // Read the code and then answer the questions below | ||

| // a) How many function calls are there in this file? Write down all the lines where a function call is made | ||
| //There are two function calls here. replaceAll and console.log |

There are more than 3 function calls.
Note: replaceAll() are called twice.
| // Line 1, line 2, line 7 and line 8 have variable declarations | ||

| // e) Describe what the expression Number(carPrice.replaceAll(",","")) is doing - what is the purpose of this expression? | ||
| //This expression removes the comma in the price from 10,000 to 10000 |

There are two operations performed in the expression.
One of them remove commas is a string, what's the other operation?
| // In line 4 we are declaring the totalMinutes. we have the remainingSeconds which is 24. Then we will do ((8784 - 24) /60) = 146 | ||
|
|
||
| // e) What do you think the variable result represents? Can you think of a better name for this variable? | ||
| // The variable result shows the total remaining duration of a movie in terms of hours, minutes and seconds |

Can you also answer the second part of question (e)?
