The typedArray.entries() is an inbuilt function in JavaScript which gives a new array iterator object containing the key and value pairs of the given typedArray object.
Syntax:
typedArray.entries()
Parameter: It does not accept any parameters.
Return value It returns a new array iterator object containing the key and value pairs of the given typedArray object.
Code #1:
<script> // Creating a typedArray Uint8Array() with some elements const uint8 = new Uint8Array([ 5, 10, 15, 20, 25, 30 ]); // Calling entries() function A = uint8.entries(); // Shifting array iterator to next element one by one // Iterator assigned to 10 A.next(); // Iterator assigned to 15 A.next(); document.write(A.next().value); </script> |
Output:
br>2, 15
Here 2 is the index of element 15.
Code #2:
<script> // Creating a typedArray Uint8Array() with some elements const uint8 = new Uint8Array([ 5, 10, 15, 20, 25 ]); // Calling entries() function A = uint8.entries(); // Shifting array iterator to next element one by one // Iterator assigned to 10 A.next(); // Iterator assigned to 15 A.next(); // Iterator assigned to 20 A.next(); // Iterator assigned to 25 A.next(); // Iterator went out of index A.next(); document.write(A.next().value); </script> |
Output:
undefined
Here output is undefined because iterator exceeds the upper bound.
