//now the log for userDetail.name will give it undefined
//because by default it will be undeifined if its a custom object  or array or any custom variables for default it has a name eg.,

//console.log(Object.name); //Object
//console.log(Array.name); //Array

const value = 34;

console.log(value.name);
//we can give name to this custom array or objects by assiging it name as below;
//and the typeof of the name will depend on the typeof the value which is assigned to it
//e.g., if we assign name a string its typeof will be string and if name is integer will be number

console.log(typeof UserDetail.name); //newData
