The TS2532 error in Typescript is triggered for both occurrences of conn.get(aa) below. However, it should be noted that both access points are protected by if(conn.has(aa)), indicating that the get operation is valid and not undefined.
const conn: Map<string, {from: string[]; to: string[]}> = new Map();
const aa = "aa";
if(conn.has(aa)) conn.get(aa).to.push("bb");
conn.set("aa", {from: [], to: []});
if(conn.has(aa)) conn.get(aa).to.push("bb");
Even when checking for existence in this manner:
if(conn.has(aa) && conn.get(aa)) conn.get(aa).to.push("bb");
Typescript still raises an issue with conn.get(aa). Can you identify the underlying problem that I may be overlooking? Thank you!
