api

These functions will throw if given a property that has an accessor (get/set). This gives you added confidence that your code is doing what you expect.

unwritable(obj, prop)

Make prop of obj unwritable. It will assign prop to object with a value of undefined if obj does not already have prop.

writable(obj, prop)

Make prop of obj writable. It will assign prop to object with a value of undefined if obj does not already have prop.

write(obj, prop, value)

Assigns value to prop of obj. It is essentially obj[prop] = value, but works on properties whether they are writable or not.

install
