You’re trying to update the value from $row right?
$row.map(r=> r.mapValues((val,key)=> key == ‘col’ ? val.map(c=> c.mapValues((v,k)=> k == ‘$’ ? $group[r[‘@id’] - 1].values()[c[‘@id’] - 1] : v)) : val))
Hi @alchemiz its not my requirement actually i had listed my requirement above i am updating value obtained from row array to group array
$group.map((g,i)=> $row.find((a,b,c)=> a[‘@id’] == i + 1) instanceof Object ? g.mapValues((val,key)=> $row.find((a,b,c)=> a[‘@id’] == i + 1)[‘col’].find((x,y,z)=> x[‘@id’] == (key.charCodeAt(0) - 64)) instanceof Object ? $row.find((a,b,c)=> a[‘@id’] == i + 1)[‘col’].find((x,y,z)=> x[‘@id’] == (key.charCodeAt(0) - 64))[‘$’] : val ) : g )
hi @alchemiz thanks for helping but thats not exact requirement actually there are two arrays in input called row and group
and each looks like this as shown below
so according to position values (rowid & colid) need to update values of second array (group array)only
expected output:
My bad, I got the charCode wrong it should be 64 😀
$group.map((g,i)=> $row.find((a,b,c)=> a[‘@id’] == i + 1) instanceof Object ? g.mapValues((val,key)=> $row.find((a,b,c)=> a[‘@id’] == i + 1)[‘col’].find((x,y,z)=> x[‘@id’] == (key.charCodeAt(0) - 64)) instanceof Object ? $row.find((a,b,c)=> a[‘@id’] == i + 1)[‘col’].find((x,y,z)=> x[‘@id’] == (key.charCodeAt(0) - 64))[‘$’] : val ) : g )
