arguments is an Array-like object accessible inside functions that contains the values of the arguments passed to that function. https://t.co/jy0paaYBW1
The logical AND (&&) operator (logical conjunction) for a set of
operands is true if and only if all of its operands are true. It is typically used with
Boolean (logical) values. When it is, it returns a Boolean value. However,
the && operat... https://t.co/tK37cLb11v
The JavaScript exception "can't define property "x": "obj" is not extensible" occurs
when Object.preventExtensions() marked an object as no longer extensible,
so that it will never have properties beyond the ones it had at the time it was mark... https://t.co/GvOmtEqQzv
The JavaScript exception "missing : after property id" occurs when objects are created
using the object

The unsigned right shift operator (>>>)
(zero-fill right shift) shifts the first operand the specified number of bits to the
right. Excess bits shifted off to the right are discarded. Zero bits are shifted in from
the left. The sign bit beco... https://t.co/cins6Hjz7I
The JavaScript exception "invalid assignment left-hand side" occurs when there was an

Starting with ECMAScript 2015, a shorter syntax for method definitions on objects
initializers is introduced. It is a shorthand for a function assigned to the method's

Both static and instance public fields are writable, enumerable, and configurable
properties. As such, unlike their private counterparts, they participate in prototype
inheritance.

The throw statement throws a user-defined exception.
Execution of the current function will stop (the statements after throw
won't be executed), and control will be passed to the first catch
block in the call stack. If no catch block exists ... https://t.co/gVhTawkMhV
