This might help:
function randomGenerator(size) {
let result = [];
let firstValue = Math.round(Math.random() * 100);
result.push(firstValue);
for (let i=0;i<size-1;i++){
firstValue += Math.random() > 0.5 ? 1:-1;
result.push(firstValue)
}
return result;
}
console.log(randomGenerator(10));
console.log(randomGenerator(13));or if you prefer to go functional you can take advantage of default values and comma operator:
const randGenerator = (size = 13,init = Math.round(Math.random() *100)) =>
Array(size).fill(0).map(e => (init += Math.random() > 0.5 ? 1:-1,init))
console.log(randGenerator(10))
console.log(randGenerator(13))
