I'm trying to push to an array even numbers inside an arrow function but I don't how to push it in to that array.
My code:
var arrayEvenNumbers = [];
var evenNumbers = (arrayEvenNumbers) => {
for (i = 2; i <= 20; i++) {
if (i % 2 == 0) {
arrayEvenNumbers.push(i);
}
}
}
console.log(evenNumbers(arrayEvenNumbers));Really I'm a beginner and I've learned a bit, but I'm trying my best
Hope someone could help me to improve
Also I don't know if I'm sending the arguments properly And I'm not native english speaker so excuse if I can't express correctly :)
this way
var arrayEvenNumbers = [];
const evenNumbers = arr =>
{
for (let i = 2; i <= 20; i++)
if (i % 2 == 0) arr.push(i);
return arr
}
console.log( evenNumbers(arrayEvenNumbers) )
console.log( arrayEvenNumbers )evenNumbers pushes it correctly, but returns undefined. You're probably looking to do:
evenNumbers(arrayEvenNumbers);
console.log(arrayEvenNumbers);
this is the code you've forgotten the return statement:
var freeArr = [];
var evenNumbers = (arr)=>{
for(i = 2; i <= 20; i++){
if(i % 2 == 0){
arr.push(i);
};
};
return(arr);
};
console.log(evenNumbers(freeArr));
