JavaScript Uint8Array.of() Method

The Uint8Array array represents an array of 8-bit unsigned integers. The values are initialized by 0. Elements in the array can be referenced by the object’s methods or using a standard syntax (by bracket notation).

The Uint8Array.of() method creates a new typed array from a variable number of arguments.

Syntax:

Uint8Array.of(el0, el1, el2, .., eln)

Parameters:

• n-elements: This method accepts the number of elements, which are basically the element for which the array is to be created.

Return Value: This method returns a new Uint8Array instance.

Example 1: In this example, the values passed are the character values that are converted to Uint8 by the method.

JavaScript

<script>
    // Creating a Uint8Array from a array by
    // Creating the array from the Uint8Array.of() method
    let uint8Arr = new Uint8Array;
    uint8Arr = Uint8Array.of('41', '51', '56', '8', '24');

    // Printing the result
    console.log(uint8Arr);
</script>

Output:

Uint8Array(5) [41, 51, 56, 8, 24]

Example 2: In this example, the values passed are the int values that are converted to Uint8 by the method. -49999 and 799 converted to 177 and 31 respectively.

JavaScript

<script>
    // Create a Uint8Array from a array by
    // Creating the array from the Uint8Array.of() method
    let uint8Arr = new Uint8Array;

    // Accepts the uint8 values
    uint8Arr = Uint8Array.of(-49999, 5, 7, 799, 8);

    // Print the result
    console.log(uint8Arr);
</script>

Output:

Uint8Array(5) [177, 5, 7, 31, 8]
