+# For Loop
+
+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 (1, 2, 3, ...) from 0 to 100.
+
+```js
+var message = ""
+```
+
+```js
+var message = ""
+
+for(var i = 0; i < 100; i++){
+    message = message + i;
+}
+```
+
+```js
+var message2 = ""
+
+for(var i = 0; i < 100; i++){
+    message2 = message2 + i;
+}
+assert(message == message2);
+```
