+Netscript Loops and Conditionals
+================================
+
+
+Loops and Conditionals
+----------------------
+
+Netscript loops and conditionals are the same as Javascript. However, the one caveat is that when declaring variables such as the
+iterator for traversing a loop, you should not use the 'var' or 'let' keyword. For reference, you can see the Javascript
+documentation for loops/conditionals here:
+
+`While loops <https://www.w3schools.com/js/js_loop_while.asp>`_
+
+`For loops <https://www.w3schools.com/js/js_loop_for.asp>`_
+
+`Conditionals (If/Else statements) <https://www.w3schools.com/js/js_if_else.asp>`_
+
+Here are some simple code examples that show the use of loops and conditionals in Netscript.
+
+The following is a while loop that runs the hack() Netscript function ten times::
+
+    i = 0;
+    while (i < 10) {
+        hack('foodnstuff');
+        i = i + 1;
+    }
+
+The following is a for loop that runs the hack() Netscript function ten times::
+
+    for (i = 0; i < 10; ++i) {
+        hack("foodnstuff");
+    }
+
+The following is a conditional that uses the getServerMoneyAvailable() Netscript function to check how much money
+exists on the 'foodnstuff' server. If there is more than $200,000 on the server, then the server will be hacked.
+Otherwise, the money available on the server will be grown using the grow() Netscript function::
+
+    if (getServerMoneyAvailable('foodnstuff') > 200000) {
+        hack("foodnstuff");
+    } else {
+        grow("foodnstuff");
+    }
