Bug 162720 – Arrow functions do not infer name from computed property but normal functions do

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Joseph Pecoraro]

Summary:
Arrow functions do not infer name from computed property but normal functions do

Test:
js> function funcName() { return "funcName" }
...
js> ({"func": function(){}}).func.name
"func"
js> ({["func"]: function(){}}).func.name
"func"
js> ({[funcName()]: function(){}}).func.name
"func"
js> ({func: ()=>{}}).func.name
"func"
js> ({["func"]: ()=>{}}).func.name
""
js> ({[funcName()]: ()=>{}}).func.name
""

Why is this? And is this actually specced anywhere? Maybe this is runtime, since evaluating funcName() must happen at runtime.
