What is Form Array | Reactive Forms | Angular 13+

Показать описание

In this lecture, you are going to learn about form arrays in Angular forms. A form array is a collection of Form controls grouped together. The Form control can be of type FormControl, FormGroup or another FormArray.

We have learned that we can also group form controls together using FormGroup. Then what is the difference between a FormGroup & FormArray? When we use FormGroup, the controls which we group together becomes a property of an object i.e. the FormGroup object.

but when we use FormArray, the controls are the elements of FormArray and not a property of it. Let's learn about FormArray in detail in this lecture.

i did just like you at 6:08 and got error
=> Property 'controls' does not exist on type 'AbstractControl'.

i used getter function to avoid the error but why that happened

If i was to console log the form array values then would it be shown as an array? I would like to use something like this where I add multiple skills but in my case i need to pass the data as a flat structure....

Hi,
Can we use FormArray to create a row with more than one data type, basically a row with more than one column and two or more data types

IvanMithun
