Hi, which warning does this fix?

[jwmann]

I know it's not a typescript project but it's good practise to use Object.assign with an empty literal, or a constant value first, especially if we're spreading a potentially undefined value.

[DanielRuf]

Shouldn't it be normally {}?

[jwmann]

You are very correct :)
Good catch

I made the incorrect assumption that pugFilters was an array. After checking, it's definitely not! 😅
