This field is connected to the formBuilder input
interests: formBuilder.array([
['', Validators.required],
])
It seems like there may be an issue with how my form is linked in the template. Is this method incorrect? How should a Form Array be properly connected to a template?
<div class="form-group" *ngFor="let interest of myForm.get('interests').value; let i = index;">
<input type="text" class="form-control" formControlName="{{ i }}">
</div>
{{ i }} represents the individual letters of the word "hobby", which is why you are seeing this.
Give {{ hobby[i] }} a shot instead
