*/
getRandomInt(min, max) : number{

function getRandomIntInclusive(min, max) {

return Math.floor(Math.random() * (max - min + 1)) + min; //The maximum is inclusive and the minimum is inclusive
}javascript get random array of integre in given range
const randomArrayInRange = (min, max, n) => Array.from({ length: n }, () => Math.floor(Math.random() * (max - min + 1)) + min);
// Example
randomArrayInRange(1, 100, 10);Generate a number range js
const range = (options) => {
const { from = 0, step = 1, to } = options;
if (!to) {
throw Error('"to" must be specified');
}
if (to <= from) {
throw Error(`"to (${to})" is lesser than or equal to "from (${from})"`);
}
return Array.from(
{ length: Math.ceil((to - from) / step) },
(_, i) => i * step + from
);
};
// Usage
const r1 = range({ to: 10 });
// [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
const r2 = range({ from: 10, to: 20 });
// [10, 11, 12, 13, 14, 15, 16, 17, 18, 19]
const r3 = range({ from: 10, to: 20, step: 3 });
