Template Literal Types

Create precise string types by combining literal types, enabling type-safe string manipulations and generating more specific string-based types.

TypeScript

Optional Chaining

Safely access nested object properties without throwing errors when intermediate properties are null or undefined

TypeScript

Type Predicates

A type predicate helps narrow down type information by defining a custom type guard function that returns a boolean to assert a specific type.

TypeScript

Intersection Types

Combine multiple types into one, creating a new type that has all properties of the intersected types. Useful for merging interfaces or creating complex type compositions.

TypeScript

Conditional Types

Advanced type system feature in TypeScript that allows creating types that depend on type conditions, enabling more flexible and dynamic type definitions.

TypeScript

Discriminated Unions

A powerful TypeScript pattern that allows creating type-safe unions with a common property to distinguish between different object shapes.

TypeScript

Index Signatures

Define flexible object types with dynamic key and value types, allowing for flexible key-value pair structures in TypeScript

TypeScript

Mapped Types

Transform existing types by mapping over their properties to create new types with modified characteristics

TypeScript

Never Type

Represents a type that should never occur, useful for exhaustive type checking and eliminating impossible scenarios

TypeScript

Readonly Modifier

Prevent modification of object properties after initialization, ensuring immutability and type safety in TypeScript.

TypeScript

Type Assertions

Allows explicitly telling the TypeScript compiler to treat a value as a specific type, overriding its inferred type

TypeScript

Type Inference Magic

TypeScript can automatically infer variable types based on their initial assignment, reducing explicit type annotations.
