How can I Alias Table name?

Question

I am using PostGreSql as database, I have tables in pgAdmin.

I want to set as alias to table myData. I have tried using AS or ALIAS but nothing works for me.

Here is my class

class Product extends Model{
constructor(conn, schema){
        super(conn, schema, "product", {
                // fields
       },true);
   }

 // function
  async getNextData() {
   try {
   const data = await this._conn.query(`
   select  *
   from  ${this._schema}."terms", ${this._schema}."myData"  ------>>>> ALIAS THIS TABLE
   where (${this._schema}."myData"."firstName" = ${this._schema}."yourData"."lastName")}
 }
}
