Q35: What are Template Literal Types?
Template Literal Types build on string literal types, allowing you to compose and manipulate string types using template literal syntax.
Combining Event String Literals
type Event = 'click' | 'hover';
type Level = 'primary' | 'secondary';
type ButtonEvent = `${Level}_${Event}`;
// Resulting Union: "primary_click" | "primary_hover" | "secondary_click" | "secondary_hover"💡 Template literal types cross-multiply combined literal union members.
Key Takeaways
- Template literal types generate string unions through string interpolation.
