Feature of#1497

Classes

Added "class" property to detect that object is class

Classes forbidden to compare because there is a lot of deep cases that might leads to bug with prototypes.

Extends MetadataCollection

Added find method of type for objects. I think it's good idea to have possibility to getts.Type by anyMetadata.

It requires in my case, because metadata doesn't cover this methods declarations:

typeFoo{bar():void}

I've noticed that it's hard to compare unions:

typeFoo={foo:number}typeBar={bar?:number}typeUnion=Foo|Barconsta={foo:1}constb={foo:2}console.assert(a===b||(a.foo===b.foo)||(a.bar===b.bar))

This will be true, because after fail onfoo prop,a.bar === b.bar becauseundefined === undefined

And this unions a lot of corner cases. I just forbidden it. Left only for primitive types.

Development & Test Environment

I've faced with problem that tests take too much time. I've added possibility to add flag that will filter tests by folder.

pnpm dev --folder=compare.equals

Also added watch mode for root:

pnpm dev
