Learn how to use Object.assign to combine multiple objects together. This pattern is helpful when writing libraries that have a set of default options where you want to allow a user to override specific options. You'll also learn how to use a third party library to recursively merge nested ...
Assigns own enumerable string keyed properties of source objects to the destination object. Source objects are applied from left to right. Subsequent sources overwrite property assignments of previous sources. 把源对象(sources)的属性分配到目标对象(object),源对象会从左往右地调用,后面对象的属性会覆盖前面...
Merge two option objects into a new one. Core utility used in both instantiation and inheritance. 先来看源码中对mergeOptions方法的注释。mergeOptions的功能是合并两个options对象,并生成一个新的对象。是实例化和继承中使用的核心方法。可见mergeOptions方法的重要性。既然这么重要,那我就带大家一行一行的来解...
In JavaScript almost everything isan object, sure, but I don't want a merge function trying to merge eg. twonew Date()instances! So many libraries use custom classes that create objects with special prototypes, and such objects all break when trying to merge them. So we gotta be careful!
