Junior Developer Central JS Practice Exercise - 14

 

Question: 

Write a Javascript program to get the largest even number from an array of integers. 

Answer: 

function largestEven (arr) {

const newArr01 = arr; 

const newArr02 = newArr01.filter(i => i % 2 === 0); 
newArr02.sort((a,b) => b - a); 

console.log (newArr02[0]); 

}

> we declare a function 'largestEven' 

> it has one parameter 'arr' which is an array of numbers

> we create a variable 'newArr01' and initialize it with value of the 'arr'

> we create another variable 'newArr02' 

> we initialize it with a value we get by using the filter method & modulo of 2, on 'newArr01'

> we then sort the 'newArr02' variable in descending order

> we console.log the first index value of the 'newArr02' to get the largest even number
