i need helps convert statement below es5 syntax. in es5? const { a, b, c = “foo” } = this.props; i suggest use explicit check if property c exists in given object or not. if not given, use default value. var = this.props.a, b = this.props.b, c = this.props.c === undefined ? 'foo' : this.props.c; the otherwise used pattern c = this.props.c || 'foo'; does not work given falsy value zero. why need check undefined (kudos to loganfsmyth mention problem in comments)? because undefined value check default parameters in function in es6. const f = (c = 'foo') => console.log(c); f(); // 'foo' f(undefined); // 'foo' f(0) // 0

i have constructor function registers event handler: function myconstructor(data, transport) { this.data = data; transport.on('data', function () { alert(this.data); }); } // mock transport object var transport = { on: function(event, callback) { settimeout(callback, 1000); } }; // called var obj = new myconstructor('foo', transport); however, i'm not able access data property of created object inside callback. looks this not refer object created other one. i tried use object method instead of anonymous function: function myconstructor(data, transport) { this.data = data; transport.on('data', this.alert); } myconstructor.prototype.alert = function() { alert(this.name); }; but exhibits same problems. how can access correct object? what should know this this (aka "the context") special keyword inside each function , value depends on how function

if want subscribers @ least x , can use startwith( x ) existing observable: streamfromlibrary.startwith( x ).subscribe( myhandler ); //i want myhandler() not wait until streamfromlibrary produce value //but called instantly x or still needs carried through intermediate replaysubject( 1 ) this? let carrier = new rx.replaysubject( 1 ); carrier.next( x ); streamfromlibrary.subscribe( value => carrier.next( value ) ); carrier.subscribe( myhandler ); or if not, there other more elegant way carry values existing streams subscription @ least 1 initial/last value? you don't need use replaysubject , should know these 2 aren't same: the startwith() operator emits preset value every observer when subscribe. the replaysubject(1) class re-emits 1 last item went through it. first value emits every observer might not same depending on pushed subject. note, there's behaviorsubject takes initial value parameter , overrides every emission works replaysubje
