Sometimes I like to just sit there and think of weird ways to accomplish things, and sometimes I come up with ideas like this, I think this could be applied to some Functional JS
// I Really dig this one const foo = { bar: { baz: [{ changeMe: 'asdf', notMe: 'asdf' }, { changeMe: 'ffff', notMe: 'asdf' }], }, }; const newArr = foo.bar.baz.map(baz => ({ ...baz, changeMe: 'swee' })); const newData = { ...foo, bar: { baz: newArr, }, }; console.log('newData', newData.bar.baz);
