True Myth / task/delay / exponential
Function: exponential() 
exponential(
options?):Generator<number>
Generate an infinite iterable of integers beginning with base and increasing exponentially until reaching Number.MAX_SAFE_INTEGER, after which the generator will continue yielding Number.MAX_SAFE_INTEGER forever.
By default, this increases exponentially by a factor of 2; you may optionally pass { factor: someOtherValue } to change the exponentiation factor.
If you pass a non-integral value as base, it will be rounded to the nearest integral value using Math.round.
Parameters 
options? 
from? 
number
Initial delay duration in milliseconds. Default is 1.
withFactor? 
number
Exponentiation factor. Default is 2.
IMPORTANT
Setting this to a value less than 1 will cause the delay intervals to decay rather than increase. This is rarely what you want!
Returns 
Generator<number>
