The Javascript BigUint64Array entries()
method returns an iterator object that contains the key/value pairs for each index in the array.
arr.entries()
Iteration using for...of loop
var arr = new BigUint64Array([12n, 5n, 8n, 130n, 44n]); var eArray = arr.entries(); for (let n of eArray) { console.log(n);/*from ww w .ja v a 2 s .co m*/ }
Alternative iteration
var arr = new BigUint64Array([12n, 5n, 8n, 130n, 44n]); var eArr = arr.entries(); console.log(eArr.next().value); // [0, 10] console.log(eArr.next().value); // [1, 20] console.log(eArr.next().value); // [2, 30] console.log(eArr.next().value); // [3, 40] console.log(eArr.next().value); // [4, 50]
