Rewrites any or_asgn and and_asgn node like
`defined?(a ||= 1)`
and
`defined?(a &&= 1)`
to a static “assignment” string node
Calls superclass method
# File lib/opal/rewriters/binary_operator_assignment.rb, line 131 def on_defined?(node) inner, _ = *node if inner.type == :op_asgn ASSIGNMENT_STRING_NODE else super(node) end end
