every_some.js

Array.prototype.Every =  function(callback){
  let i = 0, len =  this.length;
  for(i; i < len; i++){
    if(!callback(this[i])){
      return false
    }
  }
  return true
}


Array.prototype.Some =  function(callback){
  let i = 0, len =  this.length;
  for(i; i < len; i++){
    if(callback(this[i])){
      return true
    }
  }
  return false
}

let  odd  = function(ele){return ele % 2 === 1 }

console.log([1,3,5].Every(odd)); // true
console.log([1,4,5].Every(odd)); // false


console.log([1,3,5].Some(odd)); // true
console.log([1,4,5].Some(odd)); // true
console.log([2,4,6].Some(odd)); // false
