Uint8Array

About

The Uint8Array is a built-in data structure in MagiScript which allows you to store an array of 8-bit unsigned integers (values between 0 and 255). This data structure is particularly useful when you need to store a large number of small integers in a memory-efficient way.

It is a specialized array, with fix length and restricted values.

Creating a Uint8Array

You can create a Uint8Array by calling the newUint8Array function with a single argument: the size of the array. For example, the following code creates a Uint8Array with 10 elements:

let myArray = newUint8Array(10);

Accessing Array Items

You can access the elements of a Uint8Array using the bracket notation ([]). The index of the first element is 0, and the index of the last element is length - 1.

For example, the following code sets the first element of the myArray to 42:

myArray[0] = 42;

And the following code retrieves the value of the third element:

let thirdElement = myArray[2];

Querying the Length

You can query the length of a Uint8Array using the length property. For example, the following code prints the length of the myArray:

console.log(myArray.length);

Example

The following code creates a Uint8Array with 5 elements, sets their values to 0, 1, 2, 3, and 4, respectively, and then prints them:

let myArray = newUint8Array(5);

for (let i = 0; i

This will output the numbers from 0 to 5.

Conclusion

The Uint8Array is a memory-efficient data structure that allows you to store an array of 8-bit unsigned integers in MagiScript. You can create a Uint8Array by calling the newUint8Array function with a single argument: the size of the array. You can access the elements of a Uint8Array using the bracket notation, and query its length using the length property.
