function createEmployee(emp) { // ⛔️ Assignment to property of function parameter 'emp'. eslint no-param-reassign. emp.name = 'bobby hadz'; emp.salary = 500; return emp; } The ESLint rule forbids assignment to function parameters because modifying a function's parameters also mutates the arguments object and can lead to confusing behavior.

If you want to allow assignment to function parameters, then you can safely disable this rule. Strict mode code doesn't sync indices of the arguments object with each parameter binding. Therefore, this rule is not necessary to protect against arguments object mutation in ESM modules or other strict mode functions. Version

The point of that eslint rule is to avoid mutating function parameters. In general you probably want to prefer an immutable approach, which is what the rule recommends.

With this pattern, you manage a large set of parameters by removing them from the argument list and replacing them with a single "parameter object." The object has one property for each of the parameters. If the function needs to pass parameters to yet another function, it can pass along the whole object instead of passing the parameters one by ...

Anyway, compared to your solution, my proposal would only save one line of comments, so probably the current way to wrap the function between /* eslint-disable no-param-reassign */ and /* eslint-enable */ is good enough.
