Object

const obj = {
	one: 'One',
  	two: 'Two',
  	three: 'Three',
};

const result = obj.three;
console.log(result);

​x
 
const obj = {    one: 'One',    two: 'Two',    three: 'Three',};​const result = obj.three;console.log(result);

Switch..case

const input = 'three';
let result;

switch (input) {
  case 'one': {
    result = 'One';
  }
  case 'two': {
    result = 'Two';
  }
  case 'three': {
    result = 'Three';
  }
}
