angular 5 not displaying an array

Question

I've got a form, and Im adding items to an array - I want to display that array on the form below where the items are added, so the user has feedback...

If I display the full form value, I see the array just fine, however if I try to display ONLY the array, nothing shows up - and no errors.

so

{{ form.value | json }}

gives me this:

{
    myArray: ["some value","another value"]
}

and if I try to do this:

{{ form.myArray }} or {{ form.myArray.value }}

I get nothing...

Any help is appreciated

Excellent answers - thanks - however

{{ form.value.myArray }}

Only gives me the first element, I want the whole array (as a list), what might I be doing wrong now.

form.value[myArray][0] try this way

You need to use

{{ form.value.myArray }}

and if you need the first element,

{{ form.value.myArray[0] }}

then you need to loop

You can change your code to

{{form.value[myArray][0]}} //to access first element in array

You can use :

<div *ngFor = "let elm of form.value.myArray">
{{elm}}
</div>

Or to diaplay all use:

{{form.value.myArray}}
