Sprint-1/1-key-exercises/1-count.js


 // 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
+Add 1 to the value of count variable and assign  new the value to count variable


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?

yes, we can use count++ instead of count = count + 1

There is a programming term (a single word) describing operation like count++ or count = count + 1.
What is the English term for this? Using proper terminology can help you communicate more effectively with other programmers.

Sprint-1/1-key-exercises/4-random.js

+const num2 = Math.random() * (maximum - minimum + 1)
+//third operation: floor() function round a number down to the nearest whole integer
+const num3=Math.floor(num2)
+//final operation : add the value of minimum var (1) to num3 and num4 is equal to num our result


Your current description is a literal translation of the JS code. Could you explain the purpose of adding minimum to num3?

Of course ,I keep the result of "Math.floor(Math.random() * (maximum - minimum + 1))" in num3
and the main expression is "num = Math.floor(Math.random() * (maximum - minimum + 1)) + minimum;" that means I should add minimum to num3 value to get num value.
num = Math.floor(Math.random() * (maximum - minimum + 1)) + minimum
"num" is equal to "num4" is equal to "num3 + minimum"

Sorry, I meant to ask, can you explain the purpose of adding minimum to Math.floor(Math.random() * (maximum - minimum + 1)) in the original expression?

For examples,

maximum - minimum + 1 (which evaluates to 100) represents the range of the numbers we want to generate.

Math.random() * (maximum - minimum + 1) is to scale the random number from the interval [0, 1) to [0, 100).

The purpose of adding minimum is that we eant the result be greater than 1 because the value of minimum variable is 1.

Or we can say, to "shift the range by 1", or "shift the range from [0, 99] to [1, 100]".

There are more than 4 function calls.

Thank you . There are 5 functions.
Now I know that console.log() is a function too.I think it is a method and it's diffrent with function .

You are right that method and function are not the same things.

In JavaScript, a method is a function that is associated with a property of an object.

That is why console.log() is also normally considered as a function call.
