Bug 149807 – [Intl] Change the return type of canonicalizeLocaleList() from JSArray* to Vector<String>

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Sukolsak Sakshuwong]

From ECMA-402, 9.2.1, the abstract operation CanonicalizeLocaleList returns a List of Strings. From the spec, we never modify the result from CanonicalizeLocaleList(). We never expose it to the user either. This patch changes the return type of canonicalizeLocaleList() from JSArray* to Vector<String>. This should ease the workload of the GC and make the code a bit easier to read.

IMHO, using Vector<String> makes the lifetime clearer.

Use the LHS Vector<String> instead of const Vector<String>&
