Get the last element of a string in array (Javascript)

Question

Example:

var someArray = ["My Name is", "My is Name", "Name my is", "is Name my"]

I want to print the last element of each string, so:

output: is, Name, is, my

I have no idea where I should start. My first thought was to split the array and print the last index, but I didn't succeed

Use Array.map

var someArray = ["My Name is", "My is Name", "Name my is", "is Name my"];
let result = someArray.map(v => {
  let temp = v.split(" ");
  return temp[temp.length-1];
})
console.log(result);

You can use a regular expression to match the last word.

var someArray = ["My Name is", "My is Name", "Name my is", "is Name my"]
var result = someArray.map(item => item.match(/\w+$/)[0]);
console.log(result);

var someArray = ["My Name is", "My is Name", "Name my is", "is Name my"];
var lastElements = "";

someArray.forEach(str => {
  splitStr = str.split(" ");
  lastElements += splitStr[splitStr.length - 1] + ", ";
});

console.log('output: ', lastElements);

//Outputs output:  is, Name, is, my,
