在javascript中将构造函数添加回object.create的最佳方法

Question

I am fully aware of other very similar posts about object.create but I really cannot arrive to answer on this particular question. I saw a code once where it looks like it was using object.create to create new prototype and then adding back to constructor

function blah(){
   // typical constructor
}

blah.prototype = Object.create(somethingelse.prototype);
blah.prototype.constructor = blah;

Something like that .. and I tried that in chrome dev tool but did not see them as equal.. Now trying to see what that code I did see was trying to accomplish? I assume there is more difference in Object create and new(than just missing constructor?)

function blah(){
 //...
}
undefined
function somethingelse(){
 //
}
undefined
somethingelse.prototype = {
    // something else
}
Object {}
blah.prototype = Object.create(somethingelse.prototype);
Object {}
blah.prototype.constructor = blah;
blah(){
 //...
}
blah == somethingelse;
false

You've created two different objects (blah and something). I think you are confused about what inheritance means.

when you compare (==) 2 objects the reference is being evaluated - and it is different.
