Just call moment as a function without any arguments:

    moment()

For timezone information with moment, look at the `moment-timezone` package: http://momentjs.com/timezone/

How do I check which one is the current thread in Swift 3?

In previous versions of Swift it was possible to check if the current thread was the main one by doing this: 
    
    NSThread.isMainThread()

I want to use Xcode 7 with iOS 10.

As I understand, working with iOS 10 beta requires Xcode 8 beta, so I should upgrade my Xcode. However, my code can&#39;t be built by the new compiler, so I want to stay with Xcode 7.

How can I achieve that?

How to get current date using the Moment library? Not timestamp, but date. So please don&#39;t refer to that timestamp question already to be found.

I know how to get it in regular javascript, but I need a moment object with current date.

What about timezone, how to get current date in certain timezone?

My TranslationDetail component is passed an id upon opening, and based on this an external api call is triggered in the class constructor, receiving data to the state, and this data being displayed on TranslationDetail.

    //Routing:
    &lt;Route path=&quot;/translation/:id&quot; component={TranslationDetail}/&gt;
    
    //Class:    
    class TranslationDetail extends Component {
      constructor(props){
        super(props);

        this.props.fetchTrans(this.props.params.id);
      }

This all works fine if I enter the url manually. In case I&#39;d like to use react-router e.g. for displaying the next item like below the url does change, but the api call is not triggered, and the data will remain the same.

    &lt;button 
      type=&quot;button&quot;
      onClick={() =&gt; 
        browserHistory.push(`/translation/${Number(this.props.params.id)+1}`)}&gt;
      Next
    &lt;/button&gt;

Please bear in mind that I&#39;m a total beginner. The reason why this is happening is I believe that the constructor is run only once, thus no further api call is triggered.

How can I solve this?
Do I need to listed to props and call a function on change? If yes, how?

It maybe because Sets are relatively new to Javascript but I haven&#39;t been able to find an article, on StackO or anywhere else, that talks about the performance difference between the two in Javascript. So, what is the difference, in terms of performance, between the two? Specifically, when it comes to removing, adding and iterating.

Javascript Set vs. Array performance

How do I get the first and last day and time of the current month in the following format in moment.js:

&gt; 2016-09-01 00:00

I can get the current date and time like this:
`moment().format(&#39;YYYY-MM-DD h:m&#39;)` which will output in the above format.

However I need to get the date and time of the first and last day of the current month, any way to do this?

**EDIT:** 
My question is different from [this][1] one because that asks for a given month that the user already has whereas I am asking for the **current** month along with asking for a specific format of the date that is not mentioned in the other so called &#39;duplicate&#39;.

I&#39;m using the datepicker ([ng-boostrap][1]) in a popup and I would like to change the date format to `dd-mm-yyyy`. 

It seems that it can be solved by implementing a new `NgbDateParserFormatter` to replace the default `NgbDateISOParserFormatter`.

But I was wondering if there is another way.

**UPDATE:**

A small implementation of `NgbDateParserFormatter` using Moment.js
(tested with version 1.0.0-alpha.14 of ng-bootstrap):
	
	import {NgbDateParserFormatter, NgbDateStruct} from &#39;@ng-bootstrap/ng-bootstrap&#39;;
	import * as moment from &#39;moment&#39;;

	export class NgbDateMomentParserFormatter extends NgbDateParserFormatter {
		constructor(private momentFormat: string) {
			super();
		};
		format(date: NgbDateStruct): string {
			if (date === null) {
				return &#39;&#39;;
			}
			let d = moment({ year: date.year, 
                             month: date.month - 1, 
                             date: date.day });
			return d.isValid() ? d.format(this.momentFormat) : &#39;&#39;;
		}

		parse(value: string): NgbDateStruct {
			if (!value) {
				return null;
			}
			let d = moment(value, this.momentFormat);
			return d.isValid() ? { year: d.year(), 
                                   month: d.month() + 1, 
                                   day: d.date() } : null;
		}
	}
		

And in a module, you include the provider using a factory to indicate the date format as a parameter:

	---

	@NgModule({

	  ---
	  
	  providers: [
		{ 
		  provide: NgbDateParserFormatter, 
		  useFactory: () =&gt; { return new NgbDateMomentParserFormatter(&quot;DD-MM-YYYY&quot;) } 
		}
	  ]
	  
	  ---
	  
	})

Is it correct to implement a custom NgbDateParserFormatter to change the format of the input value on NgbInputDatepicker?

Deprecation warning in Moment.js - Not in a recognized ISO format

    var timeArr = moment().format(&#39;HH:mm:ss&#39;).split(&#39;:&#39;);

    var timeInMilliseconds = (timeArr[0] * 3600000) + (timeArr[1] * 60000);

This solution works, test it, but I&#39;d rather just use the moment api instead of using my own code. 

This code returns TODAYS time in milliseconds. I need it to call another function in milliseconds...Can not use the epoch. Need today&#39;s time formated in milliseconds. 9:00am = 3.24e+7 milliseconds 9:00pm = 6.84e+7 milliseconds. 


moment.js get current time in milliseconds?

Following is the scenario:

I have a `String` date and a date format which is different. Ex.:  
date: 2016-10-19  
dateFormat: &quot;DD-MM-YYYY&quot;.

I need to check if this date is a valid date.

I have tried following things

    var d = moment(&quot;2016-10-19&quot;,dateFormat);

`d.isValid()` is returning `false` every time. Does not Moment.js parse the date in the given format?

Then I tried to format the date in `DD-MM-YYYY` first and then pass it to Moment.js:

    var d = moment(&quot;2016-10-19&quot;).format(dateFormat);
    var date = moment(d, dateFormat);

Now `date.isValid()` is giving me the desired result, but here the Moment.js date object is created twice. How can I avoid this? Is there a better solution?

FYI I am not allowed to change the `dateFormat`.
