+# --description--
+
+`if` statements are used to make decisions in code. The keyword `if` tells JavaScript to execute the code in the curly braces under certain conditions, defined in the parentheses. These conditions are known as `Boolean` conditions and they may only be `true` or `false`.
+
+When the condition evaluates to `true`, the program executes the statement inside the curly braces. When the Boolean condition evaluates to `false`, the statement inside the curly braces will not execute.
+
+**Pseudocode**
+
+<blockquote>if (<i>condition is true</i>) {<br>  <i>statement is executed</i><br>}</blockquote>
+
+**Example**
+
+```js
+function test(myCondition) {
+  if (myCondition) {
+    return "It was true";
+  }
+  return "It was false";
+}
+
+test(true);
+test(false);
+```
+
+`test(true)` returns the string `It was true`, and `test(false)` returns the string `It was false`.
+
+When `test` is called with a value of `true`, the `if` statement evaluates `myCondition` to see if it is `true` or not. Since it is `true`, the function returns `It was true`. When we call `test` with a value of `false`, `myCondition` is *not* `true` and the statement in the curly braces is not executed and the function returns `It was false`.
+
+# --instructions--
+
+Create an `if` statement inside the function to return `Yes, that was true` if the parameter `wasThatTrue` is `true` and return `No, that was false` otherwise.
+
+# --hints--
+
+`trueOrFalse` should be a function
+
+```js
+assert(typeof trueOrFalse === 'function');
+```
+
+`trueOrFalse(true)` should return a string
+
+```js
+assert(typeof trueOrFalse(true) === 'string');
+```
+
+`trueOrFalse(false)` should return a string
+
+```js
+assert(typeof trueOrFalse(false) === 'string');
+```
+
+`trueOrFalse(true)` should return the string `Yes, that was true`
+
+```js
+assert(trueOrFalse(true) === 'Yes, that was true');
+```
+
+`trueOrFalse(false)` should return the string `No, that was false`
+
+```js
+assert(trueOrFalse(false) === 'No, that was false');
+```
