Nodejs Utililty Methods String Ends With

String.prototype.endsWith = function(needle) {
    return this.slice(-needle.length) == needle;

String.prototype.endsWith = function(pattern) {
  var d = this.length - pattern.length;
  return d >= 0 && this.lastIndexOf(pattern) === d;
};

String.prototype.endsWith = function(pattern) {
    return (this.substr(this.length - pattern.length, pattern.length) == pattern);
};

String.prototype.endsWith = function(pattern) {
    return (this.substr(this.length - pattern.length, pattern.length) === pattern);
};

String.prototype.endsWith = function(pattern) {
    var d = this.length - pattern.length;
    return d >= 0 && this.lastIndexOf(pattern) === d;
};

String.prototype.endsWith = String.prototype.endsWith || function ( pattern ) {
    var d = this.length - pattern.length;
    return d >= 0 && this.indexOf(pattern, d) === d;

String.prototype.endsWith = function(pattern, caseSensitive) {
  var d, s;
  if (caseSensitive) {
    d = this.length - pattern.length;
