+
+TypeScript is just like ES2015 with type-checking. All ES2015 (classes, etc) should work.
+
+## Basic types
+
+```ts
+any
+void
+
+boolean
+number
+string
+
+null
+undefined
+
+string[]          /* or Array<string> */
+[string, number]  /* tuple */
+
+string | null | undefined   /* union */
+
+never  /* unreachable */
+```
+
+```ts
+enum Color {Red, Green, Blue = 4}
+let c: Color = Color.Green
+```
+
+## Declarations
+
+```ts
+let isDone: boolean
+let isDone: boolean = false
+```
+
+```ts
+function add (a: number, b: number): number {
+  return a + b
+}
+
+// Return type is optional
+function add (a: number, b: number) { ... }
+```
+
+## Type assertions
+
+```ts
+let len: number = (input as string).length
+let len: number = (<string> input).length  /* not allowed in JSX */
+```
+
+## Interfaces
+
+### Inline
+
+```ts
+function printLabel (options: { label: string }) {
+  console.log(options.label)
+}
+
+// Note the semicolon
+function getUser (): { name: string; age?: number } {
+}
+```
+
+### Explicit
+
+```ts
+interface LabelOptions {
+  label: string
+}
+
+function printLabel(options: LabelOptions) { ... }
+```
+
+### Optional properties
+
+```ts
+interface User {
+  name: string,
+  age?: number
+}
+```
+
+### Read only
+
+```ts
+interface User {
+  readonly name: string
+}
+```
+
+### Dynamic keys
+
+```ts
+{
+  [key: string]: Object[]
+}
+```
+
+## Type aliases
+
+```ts
+type Name = string | string[]
+```
+
+## Function types
+
+```ts
+interface User { ... }
+
+function getUser(callback: (user: User) => any) { callback({...}) }
+
+getUser(function (user: User) { ... })
+```
+
+## Classes
+
+```ts
+class Point {
+  x: number
+  y: number
+  static instances = 0
+  constructor(x: number, y: number) {
+    this.x = x
+    this.y = y
+  }
+}
+```
+
+## Generics
+
+```ts
+class Greeter<T> {
+  greeting: T
+  constructor(message: T) {
+    this.greeting = message
+  }
+}
+
+let greeter = new Greeter<string>('Hello, world')
+```
+
+## Modules
+
+```
+export interface User { ... }
+```
