Order of function execution in Node async/await - node.js

Question

I have a doubt in making sure the functions run in sequence and the result from the first call is used in second call.
DB Function
async runquery(){
try {
...
const results = await db.statementExecPromisified(statement, []);
return results;
} catch (e) {
console.log("Error - " +JSON.stringify(e));
return e;
}
}
Group id
async function groupByID(approvers) {
const group = _.groupBy(approvers, 'ID');
return Object.keys(group).map(ID=> {
return group[ID].reduce((approvers, cur, idx) => ({
...approvers,
['NAME' + (idx + 1)]: cur.ID,
}), { ID});
})
Final Function
async function preparePayload() {
if(levels.length != 0 ){
let statement= `SELECT * FROM ITEMS `
list = await runquery(statement) ;
id = await groupByID(list) ;
}
let result={}
result.ID=id;
}
Output from DB : [{ID:1,NAME:'F1'},{ID:2,NAME:'F2'},{ID:1,NAME:'F3'}]
Expected Output : [{ID:1,NAME1:'F1',NAME2:'F2'},{ID:2,NAME:'F2'}]
But the output is not coming as expected.
[{
"ID": "2"
},
{
"ID": "1"
}]
I am guessing this is due to sequence of the function execution because when i do console.log(id) works as expected but when i assign to the result variable it gives unexpected output.
I am not sure if I put the question correctly .Kindly let me know if it needs to be more detail.

Answer 1

I don't see anything wrong with your code apart from two small changes
groupByID doesn't need to be async and hence don't need to be awaited
['NAME' + (idx + 1)]: cur.ID, needs to be changed to ['NAME' + (idx + 1)]: cur.NAME,
For simplicity I have removed the db call and replaced it with a promise which returns the result which you have mentioned in your post.
See the working code here - https://repl.it/repls/PepperyGrossForms
It gives me this result
{
ID: [ { ID: '1', NAME1: 'F1', NAME2: 'F3' }, { ID: '2', NAME1: 'F2' } ]
}
Hope this helps.
