How to use a switch statement with enums in TypeScript

Answer 1

enum Languages {
    TypeScript = 'A',
    Java = 'B',
    Python = 'C'
}
    
function getValue(lang: Languages) {
    switch (lang) {
      case Languages.TypeScript:
        return Languages['TypeScript'];
      case Languages.Java:
        return Languages['Java'];;

      default:
        return -1;
  }
}

console.log(getValue(Languages.TypeScript));
console.log(getValue(Languages.Java)); 
console.log(getValue(Languages.Python)); 
  
   
    
     
/*
