Question

I am writing Tetris in JavaScript as practice, and i am somewhat confused by the array notation that i am using. Here s the array that i have that stores all my pieces.

var pieces = [[[1,1],
               [1,1]],

              [[1,0],
               [1,0],
               [1,1]],

              [[0,1],
               [0,1],
               [1,1]],


              [[0,1,0],
               [1,1,1]],

              [[1,0],
               [1,1],
               [0,1]],

              [[0,1],
               [1,1],
               [1,0]]];

这种说法是什么? 这种区别与仅仅说“新阵列”有何区别?

谢谢!

Answer 1

这是一个阵容,你制造阵列,提供一面的价值观。

<代码>var a = [];与var a = 新的Array();。

但是,新的阿雷拉(Array)会给你一个空洞的阵列,却无法同时提供你可以与字面提子相处的价值。

Answer 2

它称为JSON, Javascript Object Notation。
