javascript set all values in array of object

Question

Two part question about similar problems. I\'ve got 2 different arrays,

array 1:

 array1 = [{
     name : \"users\",
     checked :          


        

Answer 1

You can use es6 fat arrow and make one liner but still it involves iteration .

array1.map(a=>a.checked=true);

array1 = [{
     name : "users",
     checked : true
   }, {
     name : "active users",
     checked : false
   }, {
     name : "completions",
     checked : false
   }]
   array1.map(a=>a.checked=true);
   console.log(array1);
