I want to add a random amount of characters before an element, repeat that element 20 times, with a diffrent amount of characters before each time. For example: An example of what I want to return is Hello World! This is time 1 Hello World! This is time 2 Hello World! This is time 3 Hello

Picking a random item from array with equal distribution
I want to pick a random item from an array at random. Is the way to go, but as far as I know this will cause a Uniform distribution to occur which means that the average is (lowbound+upperbound)/2 translated to an array with 10 elements the lower bound is the first element and the upper bound is the last element

Javascript: Assign percentage of players a random role
Let’s say I have these two arrays I would like to populate roles with, let’s say 30% of ‘Good’ and 70% ‘Bad’ strings in a random order, but always 30% of ‘Good’ roles. I am currently running this scenario which randomly creates an array, but without the percent requirements of ‘Good’ vs ‘Bad’. Can’t wrap my head around how I
Find remaining indexes and storing them as values
I’m making a small game. You have to find the ball under a randomized cup. First the images are stored in a nodeList. Then the winning cup is calculated randomly from the length of the nodeList. My problem: After the random value for winningCup has been calculated I don’t know how to find the other two indexes from the ‘images’
Can I achieve weighted randomness with a function that returns weighted booleans?
I have a method that mimics an unfair coin. You can pass in a percentage, and it tells you whether or not you succeeded by returning a boolean. So if you call it with .25, it’ll return true 25% of the time. I’m trying to figure out if I can use this function to create a weighted randomness function that
JS generate random boolean
Simple question, but I’m interested in the nuances here. I’m generating random booleans using the following method I came up with myself: Whenever random() shows up, it seems there’s always a pitfall – it’s not truly random, it’s compromised by something or other, etc. So, I’d like to know: a) Is the above the best-practice way to do it? b)
PHP/JavaScript random number
I am playing around with JavaScript and trying to choose some random images. What I’m actually trying to do: I have $totalsixes = rand(1,6); in PHP, and let’s say that chose 4. Then in JavaScript I want to show 4 images with the number 6 and 2 others with random numbers from 1-5. Here’s what I’ve tried so far: as
Javascript: Generate a random number within a range using crypto.getRandomValues
I understand you can generate a random number in JavaScript within a range using this function: Courtesy of Ionuț G. Stan here. What I want to know is if you can generate a better random number in a range using crypto.getRandomValues() instead of Math.random(). I would like to be able to generate a number between 0 and 10 inclusive, or
Custom linear congruential generator in JavaScript
I am trying to create a custom linear congruential generator (LCQ) in JavaScript (the one used in glibc). Its properties as it’s stated on Wikipedia are: m=2^31 , a=1103515245 , c=12345. Now I am getting next seed value with Although the generator seems to work, but when the numbers are tested on canvas: They seem to be horribly biased: http://jsfiddle.net/7VmR9/3/show/
