I don't understand why the output is 5, Here please explain thanks

Question

The following code will result in what value?
function test(number)
{
while(number < 5) {
number++;
}
return number;
}
alert(test(2));

Answer 1

In your example , you enter while 2<5 --> True, 2++---> number is 3 , 3<5 ---> True , 3++ --> number is 4, 4<5 --> True , 4++ ---> number is 5. 5<5 ---> FALSE , exit WHILE. So number is 5

Answer 2

Because while number is less then 5 variable will increment. It will reach 5 and stop.

Answer 3

First you will call alert(var1) that calls your function test(var2) and sends var2 ( in your example 2) to this function as argument. In function test you have while loop which you can look in 3 steps. STEP 1: Ask condition (number < 5) and if FALSE exit while, and if TRUE then STEP 2: execute statements ( you have only number++) and STEP 3: Loop again to STEP 1.

Answer 4

A box will pop-up containing the return value of number (witch is based on the arguments you pass (here you pass 2))

Answer 5

the "alert(test(2))" means that you want to create an alert window that will show the the result (the returned number) when the test function is run with a 2 passed in as the parameter.

Answer 6

ok thanks what does the alert(test(2)); mean?

its mean that your function start from 2

function test(number) = function test(2)

Answer 7

In your example , you enter while 2<5 --> True, 2++---> number is 3 , 3<5 ---> True , 3++ --> number is 4, 4<5 --> True , 4++ ---> number is 5. 5<5 ---> FALSE , exit WHILE. So number is 5

Answer 8

The following code will result in what value?
function test(number)
{
while(number < 5) {
number++;
}
return number;
}
alert(test(2));

Answare == 5
