NodeJs/Express, MySQL - Retrieve array using array of another table - mysql

Question

I have two tables: Tasks and Updates. The Tasks table contains ToDo items, while the Updates table contains updates on tasks sent by users. Updates are tied to tasks via a matching taskId value in each table. I have a set of queries that successfully pulls all the tasks matching the user's permissions (familyId) - what I need to do next is use the taskId column values pulled from the 2nd query resulting array to then complete a statement like
SELECT taskUpdate FROM updates WHERE taskId = ?
But I cannot figure out how to do this.
Here is what I currently have:
// Get all tasks
Task.getAll = (userId, result) => {
sql.query(`SELECT familyid FROM users WHERE id = '${userId}'`, (err, res) => {
if (err) {
console.log("Error selecting from USERS: ", err);
return result(null, err);
}
sql.query("SELECT * FROM tasks WHERE familyId = ?", res[0].familyid, (err, res) => {
if (err) {
console.log("Error selecting from TASKS: ", err);
return result(null, res);
}
console.log("tasks: ", res);
return result(null, res);
})
});
};
You can see in the second nested query that I retrieve all rows from "tasks" where familyId matches the result pulled from the first query. So I want to use the taskId column to now match to rows in the Updates table with the same taskId value. The trickiest thing for me is figuring out how to use the array from the 2nd query - I have a vague idea of using something like a foreach loop but have tinkered for a while with no luck.
ADDENDUM: By request, here is sample data:
TASKS table
taskId col: 200, 201...
taskName col: Test01, Test02...
UPDATES table
updateId: 1, 2...
taskId: 200, 201...
taskUpdate: "Checked garage", "Need to go to store"...
...There are more columns in each but the only columns that really matter here are taskId in each and taskUpdate in Updates.
After pulling the tasks in "SELECT * FROM tasks WHERE familyId = ?", we'll have an array of tasks. I need to use the taskId column values from that array and feed all resultant taskId values into "SELECT taskUpdate FROM updates WHERE taskId = ?" so that I can retrieve the taskUpdate values shown above.
