Class Random

constructor

• new Random(_seedOrFunction?): Random

• Create an instance of Random. If a seed is given, LFIB4 is used as generator, reproducing a series of numbers from that seed. If a function producing values between 0 and 1 is given, it will be used as generator.

  Parameters

  • Optional _seedOrFunction: number | Function

  Returns Random

Static default

getBoolean

• getBoolean(): boolean

• Returns true or false randomly

  Returns boolean

getElement

• getElement<T>(_array): T

• Returns a randomly selected element of the given array

  Type Parameters

  • T

  Parameters

  • _array: T[]

  Returns T

getIndex

• getIndex<T>(_array): number

• Returns a randomly selected index into the given array

  Type Parameters

  • T
