How can I find and update values in an array of objects?Given a changed object and an array: const item = {...} let items = [{id:2}, {id:3}, {id:4}]; Update the array with the new object by iterating over the array: items = items.map(x => (x.id === item.id) ? item : x)
const updatedObj = { ...projects[objIndex], desc: 'updated desc value'}; // make final new array of objects by combining updated object. const updatedProjects = [ ...projects.slice(0, objIndex), updatedObj, ...projects.slice(objIndex + 1), ]; console.log("original data=", projects); console.log("updated data=", updatedProjects);
Is there any way to modify a certain objects property (like the one I'm filtering out above) without creating new arrays and/or objects? Desired result: [{ bar: 1, baz: [11,22,33] }, { bar: 2, baz: [4,5,6] }]
