If there is an optional property prop1 for a react component, specifying prop1-={value} is not giving type error

[pateltejas]

Example

I have a prop named prop1, however I have a typo where I have a - after prop name, i.e prop1-={value}, but TS is not giving error. On other hand if I give in an unknown property, it does throw error. Wonder why is -= being considered valid assignment to the prop?
