What is radio in HTML?
A radio button or option button is a graphical control element that allows the user to choose only one of a predefined set of mutually exclusive options. When used in an HTML form, if no button in a group is checked, then no name–value pair is passed when the form is submitted.
Only one radio button in a group can be selected at the same time.
- Note: The radio group must have share the same name (the value of the name attribute) to be treated as a group.
- Note: The value attribute defines the unique value associated with each radio button.

checked: checked attribute in radio button is used to set the current state of a radio button. We can set it either true or false where true shows the checked state and false shows unchecked state of a radio button.
Radio buttons provide a way to give your visitors mutually exclusive choices. In a pure HTML-based form, there is virtually no work to do; the browser takes care of all the heavy-lifting. But with Angular, you need to do a little bit of the work. The key is to examine the event object. It contains information about the user’s action.
If you have a group of radio button and you want to set radio button checked based on model, then radio button which has same value and ng-model, is checked automatically. If the value of myRating is “2” then second radio button is selected.
There is a selectedDay property, which will be used to display the value of the selected radio button. There is also a days property. The days property is an array, which contains the five days of the work week. This array will be used in our template so that we don’t have have to actually create five radio buttons.
