Generates an array of n
random integers in the specified range.
- Use
Array.from()
to create an empty array of the specific length. - Use
Math.random()
to generate random numbers and map them to the desired range, usingMath.floor()
to make them integers.
代码实现
const randomIntArrayInRange = (min, max, n = 1) =>
Array.from(
{ length: n },
() => Math.floor(Math.random() * (max - min + 1)) + min
);
randomIntArrayInRange(12, 35, 10); // [ 34, 14, 27, 17, 30, 27, 20, 26, 21, 14 ]
