Constructor Parameters
Last updated
What is Constructor Parameters?
In TypeScript classes, constructor parameters provide a concise way to define and initialize class properties directly within the constructor's parameter list. By using access modifiers like public, private, or protected before a constructor parameter, TypeScript automatically creates a corresponding class property with that name and assigns the constructor argument's value to it. This streamlines the process of property declaration and initialization, reducing boilerplate code.
