jquery - Difference between find and filter

I have recently jumped into the world of jQuery. I saw the methods find() and filter() but can not figure out the difference between the two.

What exactly is the difference between the two?

Find vs Filter

Let's say you have this array:

array folks = [ 
  {name: "Bob", age: "32", occupation: "developer"}, 
  {name: "Bill", age: "17", occupation: "delinquent"}, 
  {name: "Brad", age: "40", occupation: "yes"} 
]

Find:

folks.find( fella => fella.name === "Bob")
//Returns an object: {name: "Bob", age: "32", occupation: "developer"}

Filter:

folks.filter( fella => fella.name === "Bob")
//Returns an array: [ {name: "Bob", age: "32", occupation: "developer"} ]
