Package Exports

unwritable

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (unwritable) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

example

const { unwritable, writable, write } = require('unwritable')

const obj = { foo: 123 }

unwritable(obj, 'foo')

obj.foo = 456 // does nothing
obj.foo // => 123

write(obj, 'foo', 456)
obj.foo // => 456

writable(obj, 'foo')
obj.foo = 123
obj.foo // => 123

const unwritable = require('unwritable')

const obj = { foo: 123 }

unwritable(obj, 'foo')

obj.foo = 456 // does nothing
obj.foo // => 123

unwritable.write(obj, 'foo', 456)
obj.foo // => 456

unwritable.writable(obj, 'foo')
obj.foo = 123
obj.foo // => 123

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.
