Convert VB script loops to Javascript

1. Convert vb script for loop to javascript

        For nI = 0 To 3
            window.alert("Number : " & nI )
Next

Upper bound is setting to 3 in above loop. when converting, javascript condition should be nI <= 3, (not nI < 3)

        for(var nI = 0; nI <= 3; nI++) {
            alert("Number : " + nI );
        }

out put,

    Number : 0
    Number : 1
    Number : 2
    Number : 3
