The following statements generate random integers in the range 1 to 10: If you want random integers between 0 and Max or between Min and Max, the FLOOR function is more convenient: For convenience, you can define a macro that returns a random integers between two values. Use the Set variant above to keep the first, and the Map to keep the last: Both underscore and Lo-Dash provide uniq methods. ECMAScript 6 adds the new Set Data-Structure, which lets you store values of any type. How to find the common elements of two lists? use set intersections, set(list1) & set(list2). I know this explanation is obvious but that's all I know :). And we use them to perform numerous operations. The values are uniformly distributed with various properties: You can use the UNIVARIATE and FREQ procedures in Base SAS to see how closely the statistics of the sample match the characteristics of the populations. Using the Set constructor and the spread syntax: Basically, we iterate over the array and, for each element, check if the first position of this element in the array is equal to the current position. The idea is to place each element in a hashtable and then check for its presence instantly. Hence, my claim is that when 1, 2 or 3 randomly created digits are attached to the sequential number, you award randomness to it and such randomized sequential numbers are unpredictable. However, if efficiency is your concern, then the "Pythonic" way is unlikely to be the most efficient solution. About 1/6 of the time the random number 1-6 will be repeated! for the same reason, all objects will be considered equal: otherwise, yield it and add it to the set of already seen values, In firefox v47 reduce & lut : 14.85ms vs filter & indexOf : 2836ms, In chrome v51 reduce & lut : 23.90ms vs filter & indexOf : 1066ms, generic solution by using a separate comparator function.
