The easiest form of a loop is the for statement. This one has a syntax that is similar to an if statement, but with more options:
for(condition; end condition; change){
// do it, do it now
}
Lets for example see how to execute the same code ten-times using a for
loop:
for(var i = 0; i < 10; i = i + 1){
// do this code ten-times
}
Note: i = i + 1
can be written i++
.
Create using a for-loop a variable named message
which equals the concatenation of integers (0, 1, 2, ...) from 0 to 99.
var message = "";
var message = "";
for(var i = 0; i < 100; i++){
message = message + i;
}
var message2 = ""
for(var i = 0; i < 100; i++){
message2 = message2 + i;
}
assert(message == message2);
