+## Closures
+
+A closure is the combination of a function bundled together (enclosed) with references
+ to its surrounding state (the lexical environment). In other words, a closure gives you 
+access to an outer function's scope from an inner function. In JavaScript, closures are 
+created every time a function is created, at function creation time.
+
+### Example
+```c
+function makeFunc() {
+  const name = 'Mozilla';
+  function displayName() {
+    console.log(name);
+  }
+  return displayName;
+}
+const myFunc = makeFunc();
+myFunc();
