I have the following object. This object gets assigned a new value when the user clicks on a button.
state = {
title: '',
id: '',
imageId: '',
boarding: {
id: '',
test: '',
work: {
title: '',
id: ''
}
}
}
My updated object looks like:
state = {
title: 'My img',
id: '1234',
imageId: '5678-232e',
boarding: {
id: '0980-erf2',
title: 'hey there',
work: {
title: 'my work title',
id: '456-rt3'
}
}
}
Now I want to update just work object inside state and keep everything the same. I was using Object.assign()
when the object was not nested but confused for nesting.
Object.assign({}, state, { work: action.work });
My action.work has the entire work object but now I want to set that to boarding but this replaces everything that is in boarding which is not what I want.
You should manually merge deep object properties, try following:
Object.assign({}, state, {
boarding: Object.assign({}, state.boarding, {
work: action.work
}
});
or with spread operator
{
...state,
boarding: {
...state.boarding,
work: action.work
}
}
