I need to reverse an array in javascript. However each item has to be on a new line.
function logReverse(input) {
let reverse = input.reverse();
return reverse
}
// it does not log them all on different lines
logReverse(['HTML', 'CSS', 'JavaScript'])
I need it to be returned like this IN MY CONSOLE **Each on a new line:
JAVASCRIPT
CSS
HTML
//NOT LIKE THIS
[javascript,html,css]
Please help out
In order to get this output:
JavaScript
CSS
HTML
Given the following input (Your array):
['HTML', 'CSS', 'JavaScript']
You must, reverse the original array, then loop through it calling console.log.
Try the following function:
function logBackwards(arr) {
// Reverse the input array
const reversed = arr.reverse();
// Log each item
reversed.forEach((element) => {
console.log(element);
});
}
logBackwards(['HTML', 'CSS', 'JavaScript']);
If you want to avoid using functions, a loop approach is also available.
function logBackwards(arr) {
const lastItem = arr.length - 1;
for (let i = lastItem; i >= 0; i--) {
console.log(arr[i]);
}
}
logBackwards(['HTML', 'CSS', 'JavaScript']);
Hope it helps, good luck!
To get that output, you need to either loop through the array and console.log each item:
logReverse(['HTML', 'CSS', 'JavaScript']).forEach(e => console.log(e));
Or join into a string with a newline character as the delimiter.
console.log(logReverse(['HTML', 'CSS', 'JavaScript']).join("\n"));
you can use Array.reverse()
var arr = logReverse(['HTML', 'CSS', 'JavaScript']);
var new_arr = arr.reverse();
print(new_arr);
Your function doesn't log anything, it returns the inverse so that you can do whatever you want to do with it, including logging it. You can use join to log each string in a separate line:
function logReverse(input) {
return input.reverse();
}
var rev = logReverse(['HTML', 'CSS', 'JavaScript']);
console.log(rev.join('\n'));Or, if you want the function to log it, just put the console.log code in it:
function logReverse(input) {
console.log(input.reverse().join('\n'));
}
logReverse(['HTML', 'CSS', 'JavaScript']);I guess you could do this by appending a new line symbol to each string in your array
console.log(reversedArray.map(str => `${str}\n`))
Also, if you name a function "logReversed" than it means it should reverse and log. Otherwise, it's a bit confusing.
function logReverse(input) {
console.log(input.reverse().map(str => `${str}\n`));
}
logReverse(['HTML', 'CSS', 'JavaScript'])
input.reverse().join("\n")
function logReverse(input) { console.log(input.reverse().join("\n"); }
