log(generateRandomHexColor()) 02 【数组重排序】 对数组的元素进行重新排序是一项非常重要的技巧,但是原生 Array 中并没有这项功能。代码语言:javascript 代码运行次数:0 运行 AI代码解释 const shuffle = (arr) => arr.sort(() => Math.random() - 0.5) const arr = [1, 2, 3, 4, 5]console....
1,2,3,4,5,6,7,8,9 You can use the function below to do that. functiongenerateArrayOfNumbers(numbers){return[...Array(numbers).keys()].slice(1)} generateArrayOfNumbers(numbers)will generate and return N-numbers that you pass to this function as a parameter. ...

This function can also be used to generate multiple random values from an array by using theArray.prototype.slice()function. This function returns a shallow copy of a portion of an array into a new array. We can use this function to get the firstnelements of the shuffled array. For examp...
