+# --description--
+
+In this lab, you will implement a function that checks if a string ends with the given target string.
+
+**Objective:** Fulfill the user stories below and get all the tests to pass to complete the lab.
+
+**User Stories:**
+
+1. You should create a function named `confirmEnding` that takes two parameters: the string to check and the string to check against.
+2. The function should return `true` if the first string ends with the second string, and `false` otherwise.
+3. You should not use the `.endsWith()` method; instead, use one of the JavaScript substring methods to achieve this.
+
+# --hints--
+
+You should create a function named `confirmEnding`.
+
+```js
+assert.isFunction(confirmEnding);
+```
+
+`confirmEnding` should take 2 parameters.
+
+```js
+assert.lengthOf(confirmEnding, 2);
+```
+
+`confirmEnding("Bastian", "n")` should return `true`.
+
+```js
+assert.isTrue(confirmEnding('Bastian', 'n'));
+```
+
+`confirmEnding("Congratulation", "on")` should return `true`.
+
+```js
+assert.isTrue(confirmEnding('Congratulation', 'on'));
+```
+
+`confirmEnding("Connor", "n")` should return `false`.
+
+```js
+assert.isFalse(confirmEnding('Connor', 'n'));
+```
+
+`confirmEnding("Walking on water and developing software from a specification are easy if both are frozen", "specification")` should return `false`.
+
+```js
+assert.isFalse(
+  confirmEnding(
+    'Walking on water and developing software from a specification are easy if both are frozen',
+    'specification'
+  )
+);
+```
+
+`confirmEnding("He has to give me a new name", "name")` should return `true`.
+
+```js
+assert.isTrue(confirmEnding('He has to give me a new name', 'name'));
+```
+
+`confirmEnding("Open sesame", "same")` should return `true`.
+
+```js
+assert.isTrue(confirmEnding('Open sesame', 'same'));
+```
+
+`confirmEnding("Open sesame", "sage")` should return `false`.
+
+```js
+assert.isFalse(confirmEnding('Open sesame', 'sage'));
+```
+
+`confirmEnding("Open sesame", "game")` should return `false`.
+
+```js
+assert.isFalse(confirmEnding('Open sesame', 'game'));
+```
+
+`confirmEnding("If you want to save our world, you must hurry. We dont know how much longer we can withstand the nothing", "mountain")` should return `false`.
+
+```js
+assert.isFalse(
+  confirmEnding(
+    'If you want to save our world, you must hurry. We dont know how much longer we can withstand the nothing',
+    'mountain'
+  )
+);
+```
+
+`confirmEnding("Abstraction", "action")` should return `true`.
+
+```js
+assert.isTrue(confirmEnding('Abstraction', 'action'));
+```
+
+Your code should not use the built-in method `.endsWith()` to solve the lab.
+
+```js
+assert.notMatch(__helpers.removeJSComments(code), /\.endsWith\(.*?\)\s*?;?/);
+assert.notMatch(__helpers.removeJSComments(code), /\['endsWith'\]/);
+```
+
+# --seed--
+
+## --seed-contents--
+
+```js
+
+```
+
+# --solutions--
+
+```js
+function confirmEnding(str, target) {
+  return str.substring(str.length - target.length) === target;
+}
+
+confirmEnding('Bastian', 'n');
+```
