// A Narcissistic Number is a positive number which is the sum of its own digits, each raised to the power of the number of digits in a given base. In this Kata, we will restrict ourselves to decimal (base 10).

// For example, take 153 (3 digits), which is narcisstic:
// 1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153 
// and 1652 (4 digits), which isn't:
// 1^4 + 6^4 + 5^4 + 2^4 = 1 + 1296 + 625 + 16 = 1938

function narcissistic(value) {
    // Code me to return true or false
    const valStr = value.toString(); 
    const len = valStr.length;
    console.log(valStr.split(''))
    return valStr.split('').reduce((acc,item)=>acc += Math.pow(item,len),0)===value;
    
  }

  narcissistic(7); 
  narcissistic(371);
