Small error with a small code block

Hey guys, wondering why this code only return false?
arrayOfBases is a 15 element array carrying one of 4 letters, T,G,C,A

willLikelySurvive(){
      let counterG = 0;
      let counterC = 0;
      for (let y = 0; y > arrayOfBases.length; y++){
        if (arrayOfBases[y] === 'G'){
          counterG++;  } else if (arrayOfBases[y] === 'C') { counterC++;  }
      }
      const percentageG = 100/(arrayOfBases.length - 1) * counterG
      const percentageC = 100/(arrayOfBases.length - 1) * counterC
        if (percentageG > 60){
          return true
        } else if (percentageC > 60){
          return true
        } else {return false}

    },

I used some console.log statements to figure out what was going on. Your for loop is set up wrong. Instead of:

it should be for (let y = 0; y < arrayOfBases.length; y++).
