Is there a shorter way (probably using short circuiting) to write the if part of the for-loop?

let range = new Array()
for (let i = 0; i < buckets.length; i++) {  //bucket is an array of sets. 
  if (buckets[i].size > 0) {
    range[0] = i;  //set index of the first none-empty element in buckets to be range[0]
    break;
  }
}
