Check for property values in array of objects

Question

I have this array:

var data= [{IsNormal:"true", Name:"Mike"},
         {IsNormal:"true", Name:"Tom"},
         {IsNormal:"false", Name:"Clause"},
         {IsNormal:"true", Name:"Timm"},
         {IsNormal:"true", Name:"Marta"},
         {IsNormal:"true", Name:"Dora"}];

I need to write function to check if at least one of the objects in array has property IsNormal equal to false, if there is function must return false otherwise it must return true.

Here is my implementation:

    function chekStatus(data) {
        _.each(inspections, function (value, key) {
            if (!value.IsNormal)
                return false;
            return true;
        });
    }

but I want to write something more elegant using array prototype javascript fuctions.

Answer 1

Use Array.some

 function chekStatus(data) {
     return data.some(function (item) { return !item.IsNormal; })
 }

Note, IsNormal values should be boolean, not string

var data= [{IsNormal:true, Name:"Mike"},
     {IsNormal: true, Name:"Tom"},
     {IsNormal: false, Name:"Clause"},
     {IsNormal: true, Name:"Timm"},
     {IsNormal: true, Name:"Marta"},
     {IsNormal: true, Name:"Dora"}];

Answer 2

You can use Array.some()

data.some(obj => !obj.IsNormal)
