Function to replace occurrence of certain characters with --[character]-- in a given string-CodePudding

How would I replace every occurrence of a character in a string with --[character]-- in es6 preferably.

Example string: tb23a

Pattern: t3a

Expected output: --t--b2--3----a--

CodePudding user response：

function repleceEveryChar(value, options) {
  const { chars = '', leading = '', trailing = '' } = options;
  return (chars && String(value).replace(

    RegExp(`\[${ chars }\]`, 'g'),
    match => `${ leading }${ match }${ trailing }`

  )) || value;
}

console.log(
  "repleceEveryChar('tb23a', { chars: 't3a', leading: '--', trailing: '--' }) ...",
  repleceEveryChar('tb23a', { chars: 't3a', leading: '--', trailing: '--' })
);
console.log(
  "repleceEveryChar('tb23a', { chars: 'b2', leading: '*', trailing: ' ' }) ...",
  repleceEveryChar('tb23a', { chars: 'b2', leading: '*', trailing: ' ' })
);

console.log(
  "repleceEveryChar('foobar', { leading: '*', trailing: ' ' }) ...",
  repleceEveryChar('foobar', { leading: '*', trailing: ' ' })
);
