Quick Reference

Common Patterns

Pattern 1: Parentheses in types (where a type is a combination of array, function, or union types) are used to specify the required type structure. Without parentheses, the symbol ‘|’ that constructs a union type has the lowest precedence as presented in the following example:

|

Pattern 2: A compile-time error occurs if typeReference is not a class or interface type. The semantics of the keyof type is presented in the following example:

1 class A {
2    field: number
3    method() {}
4 }
5 type KeysOfA = keyof A // "field" | "method"
6 let a_keys: KeysOfA = "field" // OK
7 a_keys = "any string different from field or method"
8   // Compile-time error: invalid value for the type KeysOfA

Example Code Patterns

Example 1 (javascript):

1 let b: boolean  // using primitive value type name
2 let n: number   // using primitive value type name
3 let o: Object   // using predefined class type name
4 let a: number[] // using array type

Example 2 (javascript):

1 let b: boolean  // using primitive value type name
2 let n: number   // using primitive value type name
3 let o: Object   // using predefined class type name
4 let a: number[] // using array type

Example 3 (javascript):

1 let b: boolean  // using primitive value type name
2 let n: number   // using primitive value type name
3 let o: Object   // using predefined class type name
4 let a: number[] // using array type
