+# ECMAScript proposal: Add memoized prefix for functions
+- [Motivation](#motivation)
+- [High-level API](#high-level-api)
+
+ ## Motivation
+
+To improve performance we use memoization. 
+Currently to create memoized functions we need to save some libraries, e.g. [memoize-one](https://github.com/alexreardon/memoize-one)
+
+ ```js
+import memoizeOne from 'memoize-one';
+
+const add = (a, b) => a + b;
+const memoizedAdd = memoizeOne(add);
+
+memoizedAdd(1, 2); // 3
+
+memoizedAdd(1, 2); // 3
+// Add function is not executed: previous result is returned
+```
+
+Would be awesome to have this functionality in the JS.
+
+ ## High-level API
+
+ ```js
+memoized function add(a, b) {
+  return a + b;
+}
+
+memoized const add = (a, b) => a + b;
+```
+
+It's also can be a good idea to apply it to existing functions:
+```
+const add = (a, b) => a + b;
+const memoizedAdd = memoized add;
+```
