Answer 1

 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: '+' }) );
