While ArrayBuffer serves as a low-level container for raw binary data, Typed Array provides a higher-level interface for accessing and manipulating specific data types within an ArrayBuffer. FAQ's Q. What is the
Javascript arrays are a type ofobjectused for storing multiple values in a single variable. Each value gets numeric index and may be any data type. 1vararr=[];//this is a shortcut for new Array(); 2 3arr[0]="cat"; 4arr[1]="mouse"; See how that syntax is so similar to the ...
We create an array containing a number, string, boolean, object, and another array. Array.of() handles all these types consistently, adding each argument as an element in the new array. $ node main.js [ 1, 'two', true, { name: 'John' }, [ 5, 6 ] ] Creating empty and single-...

object itself. TheObject.keys()method returns an array of a given object’s own enumerable properties, in the same order as that provided by a for…in loop (the difference being that a for-in loop enumerates properties in the prototype chain as well). Once you got the array of keys, ...
The returned array contains the corresponding property of the source object for each key in keys, in order. For example:permute(["a", "b", "c"], [1, 2, 0]); // returns ["b", "c", "a"]It is acceptable to have more keys than source elements, and for keys to be duplicated...

As you can see, and probably already knew, properties can be accessed a couple of different ways. However, it’s an important point that we’ll come back to in a minute. Everything in javascript is anobject. Everything.Arrays,functions, evennumbers! Because of this, you can do some rea...
