angularjs - How do i create my own watch function similar to angular in javascript -


i big fan of angular , loves two-way binding concept , watch functionality.but present firm using backbone stack , not find way include angular js backbone stack. (if there way . , good)

i want ui manipulation based on value change of simple variable.(need not object).

and if possible want extend object 1 level deep like

 var watchobj = {    variable1 : 1,    variable2 : 2  }

if of key-value pair change want ui manipulation(depending on key ).

how can achieve minimum possible javascript code.

i not recommend including angular backbone , if use backbone stack should go through tutorial (http://backbonejs.org/). maybe find things done without two-way data binding concept (http://backbonejs.org/#faq-why-backbone).

if man 'vanilla js' no framework @ all, should check object.observe functionality (https://developer.mozilla.org/en-us/docs/web/javascript/reference/global_objects/object/observe) not supported yet enough use in production (http://caniuse.com/#feat=object-observe) - , thats why there many mvc frameworks different concepts doing same in end:)

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...
