JS, как фильтровать диапазон на месте
// @ts-check
let arr = [5, 3, 8, 1, 9, 2, 4, 15, 18, 42, 39];
function filterRangeInPlace(arr, a, b) {
for (let i = 0; i < arr.length; ++i) {
if (a > arr[i] || arr[i] > b) {
arr.splice(i, 1);
i--; // since the length of the array has changed
}
}
}
filterRangeInPlace(arr, 1, 4);
console.log(arr);
