API:Removes all elements from array thatpredicatereturns truthy for and returns an array of the removed elements. The predicate is bound to thisArg and invoked with three arguments: (value, index, array). vararray = [1, 2, 3, 4];varevens = _.remove(array,function(n) {returnn % 2 =...
注意omission 会使用 baseToString 将传入的值转换成 string 类型。处理长度不足的字符串string = toString(string) let strSymbols let strLength = string.length if (hasUnicode(string)) { strSymbols = stringToArray(string) strLength = strSymbols.length } if (length >= strLength) { return string }...
if(isObject(value)){constother=typeofvalue.valueOf==='function'?value.valueOf():value;value=isObject(other)?`${other}`:other;}// 如果当前的value是否为string类型,// 不是string类型的话就判断是否为0,// 为0则直接返回,不为0就强制转换后返回if(typeofvalue!=='string'){returnvalue===0?val...

[iteratee=_.identity](Array|Function|Object|string): 每次迭代调用的函数。 它和原生JS不同, 原生JS中map是只适用于数组的方法,但是在lodash中,也可以适用于对象。 代码语言:javascript 复制 constarr=[ 1,2,3,4,5,6,7,8,9];constobj={x:10,y:20};console.log(_.map(arr,(i)=>i*2));// [...
console.log(Object.prototype.toString.call({}))// => "[object Object]"console.log(Object.prototype.toString.call([]))// => "[object Array]"console.log(Object.prototype.toString.call(newString()))// => "[object String]"console.log(Object.prototype.toString.call(newDate()))// => "[...

Lodash 通过降低 array、number、objects、string 等等的使用难度从而让 JavaScript 变得更简单。 Lodash 的模块化方法 非常适用于: 遍历array、object 和 string 对值进行操作和检测 创建符合功能的函数 本篇文章中,主要用到了以下几个: _.groupBy(collection, [iteratee=_.identity]) ...
