filter func() for Odd/Even, string separation

filter.js

let vals = [1,2,3,4,5,6,7,8,9]
let newVals =[]
newVals.push.apply(newVals, vals);

let newValsOdd = []
newValsOdd.push.apply(newValsOdd, vals);

function isEven (num) {
    return (num % 2 === 0)
}

vals = vals.filter(isEven)


console.log('method1',vals)

newVals = newVals.filter(x => (x % 2 == 0))

console.log('method 2', newVals)


 newValsOdd = newValsOdd.filter(x => (x % 2 == 1))

console.log('method 3', newValsOdd)


let text = "Hey, You are doing good code today."

let word = text.split(/\W+/);

console.log(word)

//but we get the empty string after last word, then how to remove it?

let word2 = text.split(/\W+/).filter(x=>x.length)

console.log(word2)

// OR we can get what we want

let word3 = text.split(/\W+/).filter(x=>x.length >=4)

console.log(word3)
