const length = 10000;

const testArray = Array.from({ length }, (_, i) => i)

window.testArray = testArray
window.randomIndex = Math.round(0 + Math.random() * ((length - 1) - 0))

window.testArray = window.testArray.filter(elem => elem !== window.randomIndex);

2

const index = window.testArray.findIndex(elem => elem === window.randomIndex)

window.testArray.splice(index, 1)
