Difference between component.find() component.get() in Salesforce Lightning

component.find()

Find the button component by calling cmp.find("button1") in your client-side controller, where cmp is a reference to the component containing the button.

Syntax: component.find("auraid");

find() returns different types depending on the result.

1. If the local ID is unique, find() returns the component.
2. If there are multiple components with the same local ID, find() returns an array of the components.
3. If there is no matching local ID, find() returns undefined.

component.get()

Returns the value referenced using property syntax. 

Syntax: component.get(String key) 

For example, cmp.get("v.attr") returns the value of the attr aura:attribute.
