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'
