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

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

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

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

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.

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

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.
