I have an object that I receive from an api, and each object's length are similarly long.
now, it does have a key fname and lname and I want it to become just name. I don't want to manually create an empty array and push a new one there just to change fname and lname into name.
Is there anyway I can achieve this without looping through the object and manually pushing it?
You can destructure the object while mapping it, here I have created a dummy data, let me know if this is something what you need:
var array=[{id:1, fname:'Bob', lname: 'Alice', someotherkey:'key'}]; var result = array.map(({fname, lname, ...rest})=>({name:fname+' '+lname, ...rest})); console.log(result);
.map() and the spread syntax will most likely be part of those duplicates (see the examples in the comments below the question)
