Lambdas

Lambdas

• simple expression: (x, y) ⇒ x+y

• block statements:

• the parament support object/array destructuring: (obj) ⇒ obj.field1 + obj.field2 OR ({field1, field2})

(x, y) => {
    let a = x + 1
    return a + y
}  // explicit return is required

• the lambda parameter support object/array destructuring:

  // obj is a map/object type variable
  (obj) => obj.field1 + obj.field2
  // OR
  ({field1, field2}) => field1 + field2
