如果没有看到匿名函数的威力,再看下面这个栗子: 首先补充两个python的内置函数。 filter(function, iterable) 给定一个标准(通过函数返回True or False),来过滤一个可迭代对象的元素。 map(function, iterable) 给定一个标准(通过函数返回True or False),来对一个可迭代对象的元素做映射
this filter contains two values: true and false. These value are used inPythonfor specifying the value. The true value is the first value in the list. For an example, seeAdd Fieldand theNULLABLEandNON_NULLABLEkeywords used for thefield_is_nullableparameter. ...

变异方法 (mutation method),顾名思义,会改变被这些方法调用的原始数组。相比之下,也有非变异 (non-mutating method) 方法,例如:filter(),concat()和slice()。这些不会改变原始数组,但总是返回一个新数组。当使用非变异方法时,可以用新数组替换旧数组: example1.items = example1.items.filter(function (item)...
