Nodejs Array Any Predicate any(p)

Here you can find the source of any(p)

Method Source Code

// [-1, 2, 3].any(isGreaterThanZero) => true
// [-1, -2, -3].any(isGreaterThanZero) => false
Array.prototype.any = function (p) {
    var count = 0
    for (var i = 0 ; i < this.length ; i++) {
      currentIndex = this[i]/* ww  w.  j  a v  a2  s  .  com*/
      if (p(currentIndex) === true) {
        console.log(p(currentIndex),"true is true")
        count +=1 
      };
    }
    if (count > 0) {
      return true
    }
    return false
};

// OR

Array.prototype.any = function (p) {
  return this.filter(p).length > 0;
};
