javascript - How do I remedy Browser CSP errors when using underscore.js -


i have been working on web application past couple of years , have gone make more secure adding content security policy.

i have been able remedy of issues have found, have been unable solve 1 remaining issue. csp complains error message whenever templating occurs in underscore.js believe makes use of no-no; being js code "new function(...)".

i have seen other recommendations on web, being basically:

  • use engine precompile template, eg grunt-inline-template-compile useful when have template strings inline, mine in actual html in tags, wouldn't possible without drastic content moving around.
  • switch templating engine, option more appealing previous afraid break many lines of templating syntax of underscore , huge job in itself.

are there other options people aware of?

try setting content-security-policy header unsafe-eval scripts domain temporary workaround. http://content-security-policy.com/ move template engine such handlebars possible. can have templates in separate html files , compile them javascript part of build. gives nice separation between html , js develop performance in browser users in production version

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
