How to find the longest string in an array in JavaScript? [duplicate]

Question

Here is an example array:

var friendName = ['RupaKhan','Sunny','Rohul','Mistry','Zumman','Asif','Liza','Fulo'];

How do you find the longest name in the array? But you have to use a function with return as well as find as largest name.

I tried this method but it doesn't show a result:

You are returning the length instead of name. Try saving name and check if (largeName.length > friendlist[i].length) largeName=friendlist[i] — Rajesh Dixit

var friendName = ['RupaKhan','Sunny','Rohul','Mistry','Zumman','Asif','Liza','Fulo'];

function mega(arr){
   return arr.reduce((max,name)=>{
        return name.length > max.length? name: max
    },arr[0])
}

console.log(mega(friendName))
