Removing a keyword from a value inside an object

I would like to remove the word ".com" from my object. Currently I can convert the object into a string however my filter is not working.

const items = [
{
company: 'datadog.com'
},
{
company: 'google.com'
},
{
company: 'amazon.com'
},
{
company: 'facebook.com'
}
];

var names = items.map(function(item) {
return item['company'];

});


names.toString();

 var filter = names.replace(".com", "");

 console.log(filter);

Simply use:

let names = items.map(item => item.company.replace(/[.]com$/, ''));

For each company domain name this returns the domain name with any final '.com' sequence removed.

Using the way you are doing it as a base, you can do something like this.

const items = [...youritems];

var names = items.map(function(item) {
return item['company'];

});


stringNames = JSON.stringify(names)

var filter = stringNames.replace(/.com/g, "");

filteredObject = JSON.parse(filter)

console.log(filteredObject)

But I don't think this is the safest way to go about it, or what you really want (it is not an array of objects). I would do something like this, using es6:

const items = [...youritems];

const newObject = items.map((item) => {
    const companyNoCom = item["company"].replace(/.com/g, "")
    newItem = {...item, company: companyNoCom}
    return newItem
})

console.log(newObject)

This is safer to me, it keeps it an array of objects, and it is cleaner. It uses an arrow function and does not modify the underlying objects.
