JavaScript | typedArray.length() with Examples

The typedArray.length is an inbuilt property in JavaScript which is used to return the length of the given typedArray.
Syntax:

typedArray.length

Parameters: It does not accept any parameter because it is a property not a function.
Return value: It returns the length of the given typedArray.

JavaScript code to show the working of this property:
Code #1:

<script> 
  
  // Creating a typedArray with some elements 
  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 
  document.write(b +"<br>"); 
  document.write(c +"<br>"); 
  document.write(d +"<br>"); 
  document.write(e +"<br>"); 
  document.write(f +"<br>"); 
    
</script> 

Output:

Code #2:

<script> 
  
  // Creating some ArrayBuffer with a size in bytes 
  const A = new ArrayBuffer(8); 
  const B = new ArrayBuffer(6); 
  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 
  document.write(a +"<br>"); 
  document.write(b +"<br>"); 
  document.write(c +"<br>"); 
  document.write(d); 
    
</script>
