Why can't I call an array method on a function's arguments?

Question

I have a function that can accept any number of arguments...

const getSearchFields = () => {        
    const joined = arguments.join(\'/\'); 
};

If your are getting while posting http request in angular4 user HttpHeaders. Please check below answer. After usring HttpHeaders my issue is resolved.

this.headers  = new HttpHeaders({ 'Authorization': token1, 'X-IBM-Client-Id': 'ffffdffffdd' });

values.join is not a function in the file http.es5.js Angular 4
