i using css content show - symbol in page. have used below code , working fine before. noticed content: "\f117"; not show symbol.

why happening now? has unicode representing character changed? have not included additional css file. 

.test-thiselemtn:before {     content: "\f117"; }

update1:- updating question.

how make old version fontawesome 3.2.1 work, is, -ve sign of unicode content '\f117' displayed correctly. also, has eot woff , ttf files?

update2:-

how make 2 versions of fontawesome v3.2.1 , v4.. work together?

the unicode - symbol in font awesome \f068. if doesn't load too, use font-family: fontawesome in css. 

.test-thiselemtn:before{ content: "\f068"; font-family: fontawesome;}

if don't want use font awesome can use 

.test-thiselememtn:before{ content: "\2012";}

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
