Hi everyone,
I jumped into a weird problem that has different behavior in Chrome/Node
(V8) and Firefox (SpiderMonkey).
I'm not sure if this is a known issue that I missed, or it's a new problem
that need to be reported/fixed.
The scenario is, when we try to define a variable in REPL (Chrome Dev Tool
or Node REPL) that failed first hand:
let foo = something.does.not.exist; // this is undefined
V8 will response as:
VM12688:1 Uncaught ReferenceError: foo is not defined
at <anonymous>:1:14
>From now on, everytime you try to redeclare that variable, or reassign it
with a new value, it will fail,
the variable is no longer usable.
let foo = "Something that works";
// or
foo = "Bar";
Uncaught ReferenceError: foo is not defined
at <anonymous>:1:8
And the same error when you're trying to read that variable.
With the same scenario, there's no error in Firefox. So I assume this is
the execution problem in V8.
Attached screenshots is the execution on Chrome, Node and Firefox.
