Instructions

创建一个名为myArray的多维数组。

Tests

tests:
  - text: 应该包含至少一个嵌入的数组。
    testString: assert(Array.isArray(myArray) && myArray.some(Array.isArray));

Challenge Seed

// Example
var ourArray = [["the universe", 42], ["everything", 101010]];

// Only change code below this line.
var myArray = [];

After Test

if(typeof myArray !== "undefined"){(function(){return myArray;})();}

var myArray = [[1,2,3]];
