+# --description--
+
+You can run the same code multiple times by using a loop.
+
+The most common type of JavaScript loop is called a `for` loop because it runs for a specific number of times.
+
+For loops are declared with three optional expressions separated by semicolons:
+
+`for (a; b; c)`, where `a` is the initialization statement, `b` is the condition statement, and `c` is the final expression.
+
+The initialization statement is executed one time only before the loop starts. It is typically used to define and setup your loop variable.
+
+The condition statement is evaluated at the beginning of every loop iteration and will continue as long as it evaluates to `true`. When the condition is `false` at the start of the iteration, the loop will stop executing. This means if the condition starts as false, your loop will never execute.
+
+The final expression is executed at the end of each loop iteration, prior to the next condition check and is usually used to increment or decrement your loop counter.
+
+In the following example we initialize with `i = 0` and iterate while our condition `i < 5` is true. We'll increment `i` by `1` in each loop iteration with `i++` as our final expression.
+
+```js
+const ourArray = [];
+
+for (let i = 0; i < 5; i++) {
+  ourArray.push(i);
+}
+```
+
+`ourArray` will now have the value `[0, 1, 2, 3, 4]`.
+
+# --instructions--
+
+Use a `for` loop to push the values 1 through 5 onto `myArray`.
+
+# --hints--
+
+You should be using a `for` loop for this.
+
+```js
+assert(/for\s*\([^)]+?\)/.test(__helpers.removeJSComments(code)));
+```
+
+`myArray` should equal `[1, 2, 3, 4, 5]`.
+
+```js
+assert.deepEqual(myArray, [1, 2, 3, 4, 5]);
+```
+
+# --seed--
+
+## --seed-contents--
+
+```js
+// Setup
+const myArray = [];
+
+// Only change code below this line
+
+```
+
+# --solutions--
+
+```js
+const myArray = [];
+for (let i = 1; i < 6; i++) {
+  myArray.push(i);
+}
+```
