For example, to find the largest number in an array of numbers, you could use the apply() method to pass the elements of the array to the Math.max() function: var biggest = Math.max.apply(null, array_of_numbers);

return super.set(key, value); } } TypedMap()构造函数的前两个参数是期望的键和值类型。这些应该是字符串,比如“number”和“boolean”,这是typeof运算符返回的。你还可以指定第三个参数:一个包含[key,value]数组的数组(或任何可迭代对象),指定地图中的初始条目。如果指定了任何初始条目,构造函数首先验证...
