[Proposal] Enabling `no-param-reassign` eslint rule

I've personally often feel frustrated due to being extremely hard to track an implementation after a reassignment of parameters, due to the ambiguity of types in a function that has a JSDoc declaration. I recommend enabling https://eslint.org/docs/latest/rules/no-param-reassign. There is currently `✖ 1597 problems (1597 errors, 0 warnings)`.
