+## TypeScript specific formatting
 
+For TypeScript specific code, such as within an `interface` or type annotations, we also stipulate the following standards:
+* Use semicolons as delimiters for TypeScript interfaces and types.
 
+Negative Examples:
+```typescript
+// missing semicolon delimiter
+interface Foo {
+    name: string
+    greet(): string
+}
+
+// using incorrect delimiter
+interface Foo {
+    name: string,
+    greet(): string,
+}
+```
+Positive Example:
+```typescript
+// semicolon delimiter
+interface Foo {
+    name: string;
+    greet(): string;
+}
+```
+* For type annotations, use a space after but not before.
+
+Negative Examples:
+```typescript
+let foo:string = "bar";
+let foo :string = "bar";
+let foo : string = "bar";
+
+function foo():string {}
+function foo() :string {}
+function foo() : string {}
+
+class Foo {
+    name:string;
+}
+
+class Foo {
+    name :string;
+}
+
+class Foo {
+    name : string;
+}
+```
+Positive Examples:
+```typescript
+let foo: string = "bar";
+
+function foo(): string {}
+
+class Foo {
+    name: string;
+}
+```
