While delving into the core concepts of JavaScript Objects, I came across a code snippet for copying objects:
function copy(a, b) {
for (prop in b) {
a[prop] = b[prop];
}
return a;
}
This function will replace the properties of object a
with the corresponding properties from object b
.
If we then use the following code:
function union(a, b) {
return copy(copy({}, a), b);
}
The explanation provided mentions that the union
function will prioritize the values from object a
if both objects have identical properties. Can someone help clarify this for me?
