Updating the array object in React state using immutability helper
One way to do it would be using $set
let index = 0;let newState = update(this.state, { a: { b: { [index]: { c: { $set: "new value"} } } }});this.setState(newState);
Im importing update from immutability helper here :)
this.state = { a: { b: [{ c: '', d: ''}, ...] }} this.setState((prevState, props) => update(prevState, { a: { b: { $apply: b => b.map((item, ii) => { if(ii !== n) return item; return { ...item, c: 'new value' } }) } }}))
