const convert2Obj = compose(genObj('name'), capitalizeName) 它实际上就完成了映射关系的组合,把一个数据从 String 转换成了 String 然后再转换成 Object。数学好的童鞋就知道,这就是数学上的复合运算:g°f = g(f(x)) 在我们的编程世界中,我们需要处理的其实也只有“数据”和“关系”,而关系就是函数。
使用模板字符串或者使用String()包装时,preferedType=string,即优先调用.toString()。 例如: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 [1,null,undefined,2].toString()// '1,,,2'// Uncaught TypeError: Cannot convert a Symbol value to a string[1,Symbol('x')].toString()// Uncaught Typ...
Convert all input keys to lower case. Values are not modified. If this option is enabled, all calls to nconf.get() must pass in a lowercase string (e.g. nconf.get('port')) parseValues: {true|false} (default: false) Attempt to parse well-known values (e.g. 'false', 'true', '...
3、isObject:判断数据是不是引用类型的数据 (例如: arrays, functions, objects, regexes, new Number(0),以及 new String(''))

Conditional logic: Use if-then logic, for example to decide exactly what text to display for a label based on which properties are available in the feature or even the length of the name. String manipulation: Take control over label text with things like uppercase, lowercase, and title case...

You want to parse XML as simple and easy as possible? It's dangerous to go alone, take this: var parseString = require('xml2js').parseString; var xml = "<root>Hello xml2js!</root>" parseString(xml, function (err, result) { console.dir(result); }); Can't get easier than thi...
