Solution Walkthrough for Context with Apply

By using
apply()
, we can pass an array as the context for the function execution. In this case, we pass the
numbers
array as the first argument to
apply()
, which sets
this
inside the
sum
function to the
numbers
array.
In the
sum
function, we access the first and second element of the
this
array using
[0]
and
[1]
respectively, and return their sum.
