Remove all dots except the first one from a string
- by Šime Vidas
Given a string
'1.2.3.4.5'
I would like to get this output
'1.2345'
I wrote this
function process( input ) {
var index = input.indexOf( '.' );
if ( index ) {
input = input.substr( 0, index + 1 ) +
input.slice( index ).replace( /\./g, '' );
}
return input;
}

It works but I was hoping for a slightly more elegant solution...
