Regex to match a string with specific start/end

I\'m trying to match all occurrences of strings starting with -- and ending with a single space .

The file I\'m handling is the OpenVPN manual

One thing you can do is add these to .prototype and create your own startsWith() and endsWith() functions

this way you can do string.startsWith("starts with this"); and string.endsWith("ends with this"); I'm using substring instead of indexOf because it's quicker without scanning the entire string. Also, if you pass in an empty string to the functions they return false. Reference link Here

    if ( typeof String.prototype.startsWith != 'function' ) {
  String.prototype.startsWith = function( str ) {
    return str.length > 0 && this.substring( 0, str.length ) === str;
  }
};

if ( typeof String.prototype.endsWith != 'function' ) {
  String.prototype.endsWith = function( str ) {
    return str.length > 0 && this.substring( this.length - str.length, this.length ) === str;
  }
};
