that._mUsa[that._mCon.usa[i][name]] = that._mUsa[that._mCon.usa[i][path]];

}

this is that._mCon.usa with the name and path properties

Answer 1

Object properties are accessed using .propertyname , so it should be:

that._mUsa[that._mCon.usa[i].name] = that._mUsa[that._mCon.usa[i].path];

You use [name] when the property name is dynamic, and name is a variable containing the property name.

You can use [] with a literal string, eg ['name'] and ['path'] , but there's little point to that; if the property is known, just use the normal dot notation.
