memeText.js

// Use this script on your
// preferred modern browser console

const meme = (text) => {
  return [...text.toUpperCase()].reduce((prev, curr, i, ary) => {
    return [`${prev[0]}${ary[i]}  `, `${prev[1]}\n${ary[i + 1] || ''}  `];
  }, ['','']).reduce((prev, curr) => prev + curr);
};

const result = meme('Aesthetics');

copy(result); // Text is copied to clipboard
console.log(result);

// A  E  S  T  H  E  T  I  C  S  
// E  
// S  
// T  
// H  
// E  
// T  
// I  
// C  
// S  

// The two final spaces are so
// Markdown inserts a final <br>
// (Reddit uses Markdown)

Here's a much shorter version

t=>[[...t.toUpperCase()].join(' '),...t.toUpperCase().substr(1)].join('\n');
