It was to electronics what his father's junkyards were to auto parts: a scavenger's paradise.

是乔布斯传里的一句话，从来没见过类似的说法，想请老师分析一下这个句子的成分。

上下文和翻译如下：

Jobs liked to work. He also had a newspaper route—his father would drive him when it was raining—and during his sophomore year spent weekends and the summer as a stock clerk at a cavernous electronics store, Haltek.

乔布斯喜欢工作。他曾经送过报纸，下雨的时候父亲会开车送他。在他高中第二年的时候，周末和暑假他都在一家巨大的电子器材商店哈尔泰克(Haltek)做仓库管理员。

It was to electronics what his father's junkyards were to auto parts: a scavenger's paradise sprawling over an entire city block with new, used, salvaged, and surplus components crammed onto warrens of shelves, dumped unsorted into bins, and piled in an outdoor yard.

如同他父亲那个堆满汽车零件的废品站一样，这家到处都是电子设备的商店也是拾荒者的天堂。这家商店延伸了一整个街区，那些新的、旧的、回收的、过剩的部件塞满了架子，未经分类就扔进了箱子，还有的就堆在户外的院子里。
