    因为工作中经常用到这些方法,所有便把这些方法进行了总结。

    JavaScript

    1. type 类型判断

    isString (o) { //是否字符串

    return Object.prototype.toString.call(o).slice(8, -1) === 'String'

    }

    isNumber (o) { //是否数字

    return Object.prototype.toString.call(o).slice(8, -1) === 'Number'

    }

    isBoolean (o) { //是否boolean

    return Object.prototype.toString.call(o).slice(8, -1) === 'Boolean'

    }

    isFunction (o) { //是否函数

    return Object.prototype.toString.call(o).slice(8, -1) === 'Function'

    }

    isNull (o) { //是否为null

    return Object.prototype.toString.call(o).slice(8, -1) === 'Null'

    }

    isUndefined (o) { //是否undefined

    return Object.prototype.toString.call(o).slice(8, -1) === 'Undefined'

    }

    isObj (o) { //是否对象

    return Object.prototype.toString.call(o).slice(8, -1) === 'Object'

    }

    isArray (o) { //是否数组

    return Object.prototype.toString.call(o).slice(8, -1) === 'Array'

    }

    isDate (o) { //是否时间

    return Object.prototype.toString.call(o).slice(8, -1) === 'Date'

    }

    isRegExp (o) { //是否正则

    }

    isPromise (o) { //是否Promise对象

    isSet (o) { //是否Set对象
