setValue and patchValue in angular | Reactive forms in angular | Complete Angular Tutorial

Here, you will learn setvalue and patchvalue in angular. In Angular Reactive Forms, you can set or update the value of a form control or a group of controls using the setValue or patchValue methods.

The setValue method sets the value of one or more form controls explicitly. It requires that all the form controls are passed as an object, with each key being the name of the form control and the corresponding value being the new value. If any form control is not included in the object, it will be set to null or undefined.
The patchValue method, on the other hand, allows you to update the value of one or more form controls dynamically. It is similar to setValue, but it does not require all the form controls to be passed. Instead, you can pass an object with only the form controls that need to be updated.

sir, by default values do you mean the placeholders for the input fields? I am a beginner and I don't know what's the use case of setvalues and patchvalues.
