Description of problem

Running tsc -b with repository as-is results in error:

Observations

Minor tweaks that result in successful compilation:

• Simply removing the @constructor JSDoc annotation from src/Dependency.js:7 resolves the problem. @constructor IS in fact incorrect, but it is really difficult to track down what's causing the situation when it occurs.

• Changing src/index.js to src/index.ts permits compilation without error.

• Changing src/index.js:2 from const deps = Dependency({}); to const deps = new Dependency({}); permits compilation without error.

This compiles without error in 3.6.4.
