findindex
var test = [{name: 'test1', id: 1}, {name: 'test2', id: 2}, {name: 'test3', id: 3}]; var index = test.findIndex(i => i.id === 3); const updatedObj = { ...test[index], name: 'REPLACED' }; const result = [ ...test.slice(0, index), updatedObj, ...test.slice(index + 1) ];
map
var test = [{name: 'test1', id: 1}, {name: 'test2', id: 2}, {name: 'test3', id: 3}]; var index = test.map(t => t.id).indexOf(3); const updatedObj = { ...test[index], name: 'REPLACED' }; const result = [ ...test.slice(0, index), updatedObj, ...test.slice(index + 1) ];
