Swap Global Property Values

Set temporary variables in the global namespace and restore them once complete.

Don't worry about leaving a messy trail behind you.

Usage

Assign new values to properties using swap().

import { swap } from 'swap-global'

swap('somePropertyName', 'someValue')
// will set value of `global.somePropertyName` to `someValue`

Can replace existing properties like isNaN

swap('isNaN', 'someValue')
// will set value of `global.isNaN` and store default (or previously assigned) value in memory.

Can continuously update with new values and original (pre-swap) value will still be restored.

swap('isNaN', 'someNewValue')
// will set new value of `global.isNaN` and keep original value in memory.
isNaN
// => 'someNewValue'

Check properties assigned using pending().

import { pending } from 'swap-global'

pending()
// returns all properties that have been swapped
// => ['somePropertyName', 'isNaN']

Check properties which had previous values using inMemory().

import { inMemory } from 'swap-global'

inMemory()
// returns all properties that are currently held in memory
// => ['isNaN']

Restore properties using restore(). Properties that did not have a value will be reverted to undefined.

import { restore } from 'swap-global'

restore()
// all properties changed using `swap` will be reverted back to previous values.
// typeof('somePropertyName') === 'undefined'
// typeof('isNaN') === 'function'
