I would like to extract only certain properties from a nested object. For example, I would like a new array that does not include the 'percentDone', 'rollup' & 'color'. Using the map function, I'm not sure how to access all the nested children.
const tasks = [
{
id: 1000,
name: 'Launch SaaS Product',
percentDone: 50,
startDate: '2019-01-14',
expanded: true,
children: [
{
id: 1,
name: 'Setup web server',
percentDone: 50,
duration: 10,
startDate: '2019-01-14',
rollup: true,
endDate: '2019-01-23',
expanded: true,
children: [
{
id: 11,
name: 'Install Apache',
percentDone: 50,
startDate: '2019-01-14',
rollup: true,
duration: 3,
color: 'teal',
endDate: '2019-01-17',
cost: 200,
baselines: [
{
startDate: '2019-01-13T23:00:00',
endDate: '2019-01-16T23:00:00'
},
{
startDate: '2019-01-13T23:00:00',
endDate: '2019-01-16T23:00:00'
},
{
startDate: '2019-01-13T23:00:00',
endDate: '2019-01-16T23:00:00'
}
]
}
],
baselines: [
{
startDate: '2019-01-13T23:00:00',
endDate: '2019-01-22T23:00:00'
},
{
startDate: '2019-01-13T23:00:00',
endDate: '2019-01-22T23:00:00'
},
{
startDate: '2019-01-13T23:00:00',
endDate: '2019-01-22T23:00:00'
}
]
}
],
endDate: '2019-03-16',
baselines: [
{
startDate: '2019-01-13T23:00:00',
endDate: '2019-03-15T23:00:00'
},
{
startDate: '2019-01-13T23:00:00',
endDate: '2019-03-15T23:00:00'
},
{
startDate: '2019-01-13T23:00:00',
endDate: '2019-03-15T23:00:00'
}
]
}
];
Something like this but this not include all the nested children.
var x = tasks.map(item => {
return {
name: item.name,
StartDate: item.StartDate,
etc...
children: item.children.map(x => ({
name: x.name,
StartDate: x.StartDate,
}))
}
});
I would extract it to a different function but you could also inline it like this:
var x = tasks.map(function mapper(item) {
return {
name: item.name,
StartDate: item.StartDate,
// etc...
children: item.children.map(mapper),
}
});
