Check if all properties are false

React state is as follows :

[
   {type: "Benzine", active: false},
   {type: "Diesel", active: false},
   {type: "Electricity", active: false}
]

How can I check if all active values are false.

Is there any way to do it with lodash?

You can use the every function of loadash to check if active is false for every object.

var data = [
    {type: "Benzine", active: false},
    {type: "Diesel", active: false},
    {type: "Electricity", active: true}
];
// First argument is the data and second argument is the predicate to check
var res = _.every(data, {active: false}); // Returns true if all elements pass the predicate match else false.
document.getElementById("data").innerHTML  =  res;

You can use the following to test wether every active property is true:

    var arr = [
       {type: "Benzine", active: false},
       {type: "Diesel", active: false}, 
       {type: "Electricity", active: false}
    ]

    console.log(arr.every(obj => obj.active));

var arr = [
       {type: "Benzine", active: true},
       {type: "Diesel", active: true}, 
       {type: "Electricity", active: true}
   ]

   console.log(arr.every(obj => obj.active));

    var arr = [
       {type: "Benzine", active: false},
       {type: "Diesel", active: true}, 
       {type: "Electricity", active: false}
    ]

    console.log(arr.every(obj => obj.active));
