I am trying to change the value of single key in an associative array which is inside another assoc array using javascript.
I have an array like this:
let arr = [{
id: 4,
name: 'test',
docs: [{
id: 1,
name: 'abc'
},{
id: 2,
name: 'xyz'
}]
}, {
id: 8,
name: 'test2',
docs: [{
id: 5,
name: 'abc'
},{
id: 7,
name: 'xyz'
}]
}]
I want to change the value of name of xyz to xyz (test), where test is name key of parent object and get final array as Output:
[{
id: 1,
name: 'abc (test)'
},
{
id: 2,
name: 'xyz (test)'
},
{
id: 5,
name: 'abc (test2)'
},
{
id: 7,
name: 'xyz (test2)'
}]
I am using approach.
let docs = new Array();
arr.forEach((item, index) => {
let docx = item.documents.map(item1 => {
item1.name = item1.name + " ("+item.name+")";
});
docs.push(docx);
});
return docs;
this is returning array of undefined array.
