打字稿：谁能解释这个代码块

Question

I'm trying to understand existing code block in a project, I'm a Javascript developer and I'm not aware of TypeScript alot

Code block::

ViewModel newPropertyAddress = new ViewModel(){name, previousPro = oldValue }

Answer 1

That is not valid TypeScript as far as I am aware. ViewModel newPropertyAddress is not how you create a new variable of type ViewModel in TypeScript - that would be const newPropertyAddress: ViewModel .

To say nothing of the bizarre curly brace block, which is technically speaking valid TS, but I can't imagine who would write any code like that, or why.

Answer 2

This is how i learned and solved it.

ViewModel newPropertyAddress = new ViewModel();
newPropertyAddress.name = getName();
newPropertyAddress.previousPro = oldValue;
