谁能帮我把它变成 js 语法？

Question

this is my code that I need to convert from Python to JS, I tried a lot of ways I found online but can't seem to find a working one. the code works in Python but not in JS, the probability to get ['1','1','1'] is 0.2 and so on. thanks!

options = [["1","1","1"],["39","39","39"],["10","10","10"],["19","19","19"],["1","1","1"],"2", "lose"]
result = random.choices(options, weights = [0.2,0.8,1,1,2,75,20])[0] 

Answer 1

This should do the trick.

 var random = { int (min, max) { return Math.floor(Math.random() * (max - min) ) + min; }, choices (options, weights) { // find the total weight. Can also be done by looping let totalWeight = weights.reduce((a, b) => a + b); // getting a random number from 0 till totalWeight let randomNumber = this.int(0, totalWeight); // resetting the totalWeight totalWeight = 0; for (let i in options) { totalWeight += weights[i]; // once the weight hits the randomNumber, return the element if (totalWeight >= randomNumber) { return options[i]; } } // otherwise, return the last element return options[options.length - 1][0]; } } var options = [["1","1","1"],["39","39","39"],["10","10","10"],["19","19","19"],["1","1","1"],"2", "lose"]; var result = random.choices(options, [0.2,0.8,1,1,2,75,20]) console.log(result);
