WebThe goal is to generate "random" outputs for a fixed integer input, but (and this is the clincher) to generate the same random output every time the same random input is put in. The idea here is that the function will generate the world the same way every time, so we don't need to store anything; the function itself is the storage. WebDec 23, 2024 · We have the option of providing our own seed or allowing the computer to use the system clock time as the seed to produce the required sequence of numbers: var seed = 3; var random = new Random(seed); Using the same seed for separate Random objects within the same environment will generate the same series of random numbers.
