Hi, I'd like to be able to update an object inside an array at a given index, in an immutable way. Converts value to a plain object flattening inherited enumerable string keyed Teams. It's highly recommended to use a module bundler like webpack, rollup, or browserify.The immutable npm module works without any additional consideration. Overview.
