Immutable Js Map To Array at Taylah North blog

Immutable Js Map To Array. For example, brian lonsdorf demonstrates using ramda lenses to blend native objects/arrays with immutable.js maps/lists in his article lenses with immutable.js. There is a performance hit from using fromjs() and tojs(). It's because the sr is an array of object, so if you use.fromjs to convert it, it becomes list of map. Any javascript object may be used as a key, however strict identity is used to evaluate. In addition to the spread operator, many of the array methods also create a new array and therefore treat an array as immutable. If you are only interested in a shallow comparision you could set initial state. Plain javascript object or arrays may be nested within an immutable.js collection, and getin() can access those values as well: The map method creates a new array using the results of calling a mapping function on every element in the original array. Other array methods modify the array in place and are. Consider a trivial mapping function doubling a number.
