1143279 - TypeError#toString() round-trips strings using single quotes from named function but double quotes from IIFE

Status: RESOLVED WORKSFORME

(Core :: JavaScript Engine, defect)

Description

[Chris Peterson [:cpeterson]]

If the TypeError is thrown from the top-level or a named function, the exception string uses single quotes. If thrown from an IIFE, the exception string uses double quotes.

Is this a dupe of WONTFIX'd bug 346898?

let o = {}; o[`1.1`].random_prop;
TypeError: o['1.1'] is undefined

function f() { let o = {}; o[`1.1`].random_prop; }
f()
TypeError: o['1.1'] is undefined

(function() { let o = {}; o[`1.1`].random_prop; })()
TypeError: o["1.1"] is undefined

No longer reproducible, therefore resolving as WFM.
