javascript - Difference between Object.assign and just assign -

i know difference between this:

object.assign(otherobject, {   somenewproperty: '' });

and

otherobject.somenewproperty = '';

and.. 1 faster?

thanks.

the object.assign() method used copy values of enumerable own properties 1 or more source objects target object. return target object.

whereas otherobject.somenewproperty = ''; method directly assign value property of object.

ofcourse second method, assigns value object dot notation faster.
