I recall seeing a v8 dev talking about how try-catch prevents certain types of optimisations on the code it contains, and I notice that for many sites (coming from nodejs perspective) V8 can spend a lot of time in JSON.parse… and because it throws if it comes across some malformed JSON, you always have to have the thing inside a try/catch… therefore always suffering from not being able to optimise due to try catch.
Is that a valid concern? -- v8-users mailing list [email protected] http://groups.google.com/group/v8-users
