Question

Quizplus · Accepted Answer

A) "br549" is a valid JavaScript variable name because it starts with a letter and does not contain any spaces or illegal characters. Variables in JavaScript must begin with a letter, underscore (_), or dollar sign ($), and cannot start with a number. "Tax Rate" contains a space, which is not allowed. "37AB" starts with a number, which is also not allowed. "0123" is purely numeric, which is not a valid format for variable names.
