Using Javascript to extract the initials of names

Question

Using Javascript to extract the initials of names

I am looking for a way to shorten Person and group names

Person :

Robert Smith
David Smith
James Johnson
William

If I use this code snippet:

if(Name.split(",").length === 1)
  return Name.trim().split(" ").map(x => x[0]).reduce((acc, curr) => acc + curr) 
else 
  return ''

The output will be:

RS
DS
JJ

In another scenario, there are sets of names such as:

Robert Smith, David Smith
James Johnson, Robert Smith

In this case, if any comma is found, I would like to return RD in the first case and JS in the second case

Answer №1

It appears that there may be some confusion in your question. From what I understand, you are looking to extract the initials of the first and last name in one scenario, and the initials of each name in another scenario.

Please see the potential solution below:

const scenario1 = "Robert Smith";
const scenario2 = "Robert Smith,David Smith";

function getInitial(data) {

  const chunks = data.split(",");
  
  if ( chunks.length > 1) {
    const initials = [];
    chunks.forEach(chunk => initials.push(chunk[0]));
    return initials.join('');
  } else {
    const [fname, lname] = chunks[0].split(' ');
    return `${fname[0]}${(lname ? lname[0] : '')}`;
  }

}

console.log(getInitial(scenario1))
console.log(getInitial(scenario2))
