How to create an array of objects with one of the properties being an array from a single array-CodePudding

I got this array:

[
name1, 
[email protected],
[email protected],
[email protected],
name2,
[email protected],
name3,
name4,
[email protected],
[email protected],
[email protected],
[email protected],
[email protected],
]

From that array I need to parse it and create an array like the following:

[
{ dlName: < element without @ > , members: [<elements with @ >]}, 
{ dlName: < element without @ > , members: [<elements with @ >]}, 
{ dlName: < element without @ > , members: [<elements with @ >]}
]

example:

[
  HR,
  [email protected],
  [email protected],
  [email protected],
  cyber,
  [email protected],
  [email protected],
  accessibility,
  accounting,
   [email protected],
   [email protected]
]

output:

[
{ dlName: HR , members: [[email protected],[email protected],[email protected],]}, 
{ dlName: cyber , members:[[email protected],[email protected],]}, 
{ dlName: accesibility , members: []},
{ dlName: accounting , members: [[email protected],[email protected]]}
]

How can I get this output, everything I tried does not work for me needs.

Thanks in advance

CodePudding user response：

You could reduce the array by having a look to the strings.

If you got an '@' add the string to the last object to members, otherose add a new object to the result set.

const
    data = ['name1', '[email protected]', '[email protected]', '[email protected]', 'name2', '[email protected]', 'name3', 'name4', '[email protected]', '[email protected]', '[email protected]', '[email protected]', '[email protected]'],
    result = data.reduce((r, v) => {
        if (v.includes('@')) r[r.length - 1].members.push(v);
        else r.push(({ dlName: v, members: [] }));
        return r;
    }, []);

console.log(result);
