${some_var} 中的$是什么意思

search(term:string) {
        let promise = new Promise((resolve, reject) => {
        let apiURL = `${this.apiRoot}?term=${term}&media=music&limit=20`;
        this.http.get(apiURL)
            .toPromise()
            .then(
            res => { // Success
                console.log(res.json());
                resolve();
                   }
                 );
        });
        return promise;
    }
