linux - How to handle an Error correctly using Javascript? -


when want send , error using javascript do:

throw new error()

it works, if pass number, example:

throw new error(500)

the result is:

error: 500

where 'error: ' string.

i have function handle errors, function must know code of error, how retrieve it? have parse string? :-(

thank you.

if throw error way, text between parenthesis becomes error message. can throw using a custom error object.

a useful link: the art of throwing javascript errors
