Join data from two tables in javascript

What I manage to do is filter my first table from where I get the first data next to an "id" that I use to filter a second table, the issue is that I can not join them in a single array. An example would be something like this first filtered data

idpersona / dias / hora
1        / lunes / 8:00
2       / martes / 9:00

my second table would have the data of these people

idpersona / nombre / etc
1        / miguel / ...
2        / fernando / ....

What I need is for me to stay together idpersona / dia / hora / name / etc

But using push I'm left like this

(index) /idpersona / dias / hora / nombre   / etc
0       / 1        / lunes / 8:00 /         /
1       / 2        / martes / 9:00 /        /
2       /          /       /      / miguel  / 
3       /          /       /      / fernando /

I do not know what I'm missing if you can give me a hand please!

SOLVED, after denying a whole day of foolishness I achieve it

for(let i in persona){       
      this.db.executeSql(this.misql,[persona[i]['personaid']]).then(
            response =>{                 
              for (let index = 0; index < response.rows.length; index++){          
              persona[i]['nombre'] = response.rows.item(index)['nombre'];
              persona[i]['telefono'] = response.rows.item(index)['telefono'];

I used to use the PUSH option and for that reason it was added below, instead I now go through [i] and I am adding new fields to the object, for now it is the solution that I found is probably not the best code but I managed to get it return my arrangement with the data as I needed
