Date: 2014oct15 Language: javaScript Q. javaScript: How can I make an array of unsigned 32-bit numbers? A. As it turns out there is a built-in class for that. Example 1:

let a = new Uint32Array(256); // Make an empty array of 256 entries a[100] = 12; // As you'd expect... sets element 100 to 12. console.log('value=' + a[100]); // print value of element 100

Example 2:

// Create an 4 element array with values 100, 200, 400, 800 let a = new Uint32Array([100, 200, 400, 800]);

Warning! the array does not grow. So this will NOT work:

let a = new Uint32Array(); a[5] = 44; // Does not work.

You can use the set() member to change the array after its created. Normally numbers in javaScript are 64-bit floats.
