var A = new Uint8Array([5, 10, 15, 15, 5, 20, 10]);
var B = new Uint8Array([5, 10]);
var C = new Uint8Array([5, 10, 15]);
var D = new Uint8Array([5, 10, 15, 15, 5]);
var E = new Uint8Array([5, 10, 15, 15, 5, 20]);

// Calling length() function
b = A.length
c = B.length
d = C.length
e = D.length
f = E.length


// Printing the length of the typedArray
console.log(b);
console.log(c);
console.log(d);
console.log(e);
console.log(f);

const C = new ArrayBuffer(16);
const D = new ArrayBuffer(32);

// Creating some typedArray with the above sizes
// of the buffer
const E = new Uint8Array(A);
const F = new Uint8Array(B);
const G = new Uint8Array(C);
const H = new Uint8Array(D);

// Calling length property
a = E.length
b = F.length
c = G.length
d = H.length

// Printing the length of the typedArray
console.log(a);
console.log(b);
console.log(c);
console.log(d);

Output:
