How can I reverse an array in JavaScript, with each item on a new line?
function logReverse(input) {
let reverse = input.reverse();
return reverse;
}
// The current implementation does not display items on different lines
logReverse(['HTML', 'CSS', 'JavaScript']);
I want the output to be like this when logged IN MY CONSOLE **Each on a new line:
JAVASCRIPT
CSS
HTML
//NOT LIKE THIS
[javascript,html,css]
Any suggestions or solutions are appreciated. Thank you!
To achieve the desired result:
React
Sass
JavaScript
Using the supplied input (Your array):
['JavaScript', 'Sass', 'React']
You need to reverse the original array and iterate through it, using console.log.
You can try employing this function:
function logReversed(array) {
// Reverse the array provided
const reversedArray = array.reverse();
// Output each element
reversedArray.forEach((item) => {
console.log(item);
});
}
logReversed(['JavaScript', 'Sass', 'React']);
If you prefer not to use functions, an alternative approach with a loop is also feasible.
function logReversed(array) {
const lastIdx = array.length - 1;
for (let i = lastIdx; i >= 0; i--) {
console.log(array[i]);
}
}
logReversed(['JavaScript', 'Sass', 'React']);
Hoping this solution proves helpful. Best of luck!
In order to achieve that result, you can either iterate through the array and use console.log for each element:
logInReverseOrder(['HTML', 'CSS', 'JavaScript']).forEach(item => console.log(item));
Alternatively, you can concatenate the elements into a single string using a newline character as the separator.
console.log(logInReverseOrder(['HTML', 'CSS', 'JavaScript']).join("\n"));
To reverse an array, you can utilize the Array.reverse() method.
var arr = logReverse(['HTML', 'CSS', 'JavaScript']);
var new_arr = arr.reverse();
print(new_arr);
The function provided does not log the result but instead returns it, allowing for further manipulation such as logging. One option is to use the join method to log each string on a separate line:
function logReverse(input) {
return input.reverse();
}
var rev = logReverse(['HTML', 'CSS', 'JavaScript']);
console.log(rev.join('\n'));Alternatively, if you prefer the function to directly log the result, you can include the console.log statement within the function itself:
function logReverse(input) {
console.log(input.reverse().join('\n'));
}
logReverse(['HTML', 'CSS', 'JavaScript']);One possible approach is to add a line break symbol at the end of each string in your array.
console.log(reversedArray.map(str => `${str}\n`))
In addition, if you name a function "logReversed", it implies that it will reverse and display the result. Otherwise, it might be confusing.
function logReverse(input) {
console.log(input.reverse().map(str => `${str}\n`));
}
logReverse(['HTML', 'CSS', 'JavaScript'])
