better way push array of an object to array of an object based on the same id?

hi I want to push array of an object to array of an object so the the new property will push to the array of object based on the same _id
this is the original data :

const data =[
             { 
              foo:foo1,
              data:{
                   _id:"a1",
                   man:2
                  }
            },
            { 
              foo:foo1,
              data:{
                   _id:"a1",
                   man:2
                }
             }
           ]

this is the data that I want to put on my original data

const d = [{
             _id:"a1",
             women:4,
           }]

And the desired output is:

      const data =[
             { 
              foo:foo1,
              data:{
                   _id:"a1",
                   man:2,
                   women:4
                  }
            },
            { 
              foo:foo1,
              data:{
                   _id:"a1",
                   man:2,
                   women:4
                }
             }
           ]

I think it can be done using for loop and check if the _id is the same and push it to the object, but is there any better way? or using lodash? any idea? thanks in advance

>Solution :

You can try this!

const d = [{
             _id:"a1",
             women:4,
           }
           ]
    
const data =[
             { 
              foo:"foo1",
              data:{
                   _id:"a1",
                   man:2
                  }
            },
            { 
              foo:"foo1",
              data:{
                   _id:"a1",
                   man:2
                }
             }
           ]    
var arr = data.map(function(obj, i){
    d.map(function(o,i){
    if(obj.data._id == o._id)
    {
        obj.data.women = o.women;
    }
    });
    return obj;
});

console.log(arr);
