I want to create a .txt file which contains my array, using fs.
My array looks like this:
const array = [1111, 2222, 33333]
The code below allows me to write in the file and seperate each entry with a comma but I cant get them on a new line. Neither using \n nor \r\n
await fs.writeFile('Participants.txt', `${array}, \r\n`);
Thanks for your help in advance.
Is something like this what you are looking for?
const array = [1111, 2222, 33333]
var arrayLength = array.length;
for (var i = 0; i < arrayLength; i++) {
fs.appendFile('Participants.txt', `${array[i]}\n`);
}
What you are looking for is array.join():
const text_string = eligible.join('\n');
await fs.writeFile('Participants.txt', text_string);
In the example above I separated out the string you want to write to the file into a variable for clarity so that it is obvious what's going on. Of course you could skip the extra variable and just do eligible.join('\n') directly in the fs.writeFile() but I wanted to make it clear that this feature has nothing to do with fs nor any string syntax nor any function argument syntax. It is simply a feature of Arrays.
