Function (JavaScript)

An object that represets a series of instructions.

Basic Example

function hello() {
  return 'hello world';
}
hello();

'hello world'

const helloAgain = () => {
  return 'hello again';
};
helloAgain();

'hello again'

If no {}s are used the expression is implicitly returned.

const foo = () => 'bar';
foo();

'bar'
