resolves #6360

Proposed Changes

Fairly minor refactoring to bypass some typescript errors appearing on dependent projects with certain tsconfig settings.

Behavior Before Change

N/A. No behavioral changes.

Behavior After Change

N/A. No behavioral changes.

Reason for Changes

Test Coverage

Existing tests should cover my changes:

• run_node_test.js covers Generator#workspaceToCode
• toolbox_test.js has "parseToolbox" suite covers parseToolboxTree
• block_test.js has "toString" suite to test Block#tostring

Ran npm run test and all existing tests passed.

Hello and thank you for sending us this useful pull request; it is appreciated!

It mostly looks great, but there is one place where I am hoping you might be able to suggest a better choice of name, and another where I think there is an actual error in our type definitions (maybe several errors) that should be fixed.

Assigning to @maribethb for follow-up review as I will be on annual leave until 20th August.

@btw17 commented that #6360 should be fixed with #6362. This PR will still clean up some code, but not nearly as useful after that fix is merged.

[ktbytechibong]

Ok, addressed comments in the PR. Thanks.

Thanks for the fixes! LGTM =) If/once CI passes I'll go ahead and merge this, and it will go into our next release!
