+.. _lang-while:
+
+``while``
+=========
+
+Syntax
+------
+
+::
+
+ while (expression) {
+ // block of code
+ }
+
+Description
+-----------
+
+``while`` loops will repeat the statements inside their associated
+block of code until the expression inside the parentheses becomes
+:ref:`false <lang-constants-false>`. Something must change the tested
+expressions' value, or the ``while`` loop will never exit. This could
+be in your code, such as an incremented variable, or an external
+condition, such as testing a sensor.
+
+Example
+-------
+
+::
+
+ var = 0;
+ while(var < 200) {
+ // do something repetitive 200 times
+ var++;
+ }
