TypeScript 3.5 Support

[gcalison]

🚀 feature request

Relevant Package

This feature request is for all Angular projects (components, cli, etc).

Description

Angular does not support TypeScript 3.5.

Describe the solution you'd like

Add support for TypeScript 3.5.

TypeScript 3.5 sidenote from here:
"Note that this release shifts TypeScript from a 2-month release cycle to a 3-month release cycle."
Hopefully this new release cycle will make it easier for Angular to adopt releases faster.😉

Hope this will make it into v8.1 because:

One of the main highlights of this release is actually a fix for a type-checking bug the TypeScript team introduced in v3.4 that caused longer build times and made TypeScript/JavaScript editor operations "unbearably slow".

[GoGoris]

Support for Object.fromEntries was also added. This is already supported in most major browsers so it would be a nice feature.

Looks like 8.1 just entered RC phase, which just means bug fixes until release, I believe. So no TS 3.5. 😭

What is the usual lag time between TypeScript releases and Angular support? Is this delay normal?

[blogcraft]

Any idea when will this be merged? It seems the commit is pending various checks.

fixed in 8.2.0 see #31615

[blogcraft]

Package "@angular-devkit/build-angular" has an incompatible peer dependency to "typescript" (requires ">=3.1 < 3.5", would install "3.5.3")
