So, you’ve proposed two functions that look like they are primarily designed to work with arrays, but they should return intelligent results if you pass them something other than an array.<\/p>\n

So, right away, you can’t use the Array.prototype<\/code> method because if the data is not an array, that method won’t exist on the object and you won’t get the behavior you have currently coded.<\/p>\n

So, it really comes down to whether they should be global functions or namespaced functions on your own global object.<\/p>\n

When in doubt, fewer global symbols is generally the right answer because more global symbols make it more likely you may have a conflict with other code you might include in your project.<\/p>\n

I would suggest this revised implementation of your namespace object:<\/p>\n

var Helper = {\n    isEmpty: function (obj) {\n        return !obj || (Array.isArray(obj) && obj.length === 0);\n    },\n    pushArray: function (arr1, arr2) {\n        if (Array.isArray(arr1)) {\n            if (Array.isArray(arr2) {\n               \/\/ push one array onto the end of the other\n               arr1.push.apply(arr1, arr2);\n            } else if (arr2 !== undefined) {\n               \/\/ push a value onto the array\n               arr1.push(arr2);\n            }\n        }\n    }\n}\n<\/code><\/pre>\n
In isEmpty()<\/code>, I’ve removed the obj === null || obj === undefined<\/code> checks because they will never be hit because !obj<\/code> will already catch those.<\/p>\n
In pushArray()<\/code>, I’ve made it so a falsey value passed in arr2<\/code> (such as 0<\/code>) can be pushed into the array which your code would not allow.<\/p>\n<\/p><\/div>\n
