How to replace undefined value with a string

Question

I tried to use this code:

if((data.memberData.workStreak || 0) >= 5){
            won+=400;
            embed.addField(message.language.get("WORK_CLAIMED_HEADINGS")[0], message.language.get("WORK_CLAIMED_SALARY", won))
            .addField(message.language.get("WORK_CLAIMED_HEADINGS")[1], message.language.get("WORK_AWARD"));
            data.memberData.workStreak = 0;
        } else {
            for(let i = 0; i < award.length; i++){
                if (typeof i === 'undefined') {
                   return '<:b_:682865394637078531>';
                }
                if(data.memberData.workStreak > i){
                    let letter = Discord.Util.parseEmoji(award[i]).name.split("_")[1];
                    award[i] = ":regional_indicator_"+letter+":";
                }
            }

But it did absolutely nothing.

Any help?

+ (letter || 'string') +

You can simply use the OR operator and print string instead of undefined. In below statement if a is undefined then it will store empty string in a instead of undefined.

a = a || ''

Replace your line with below line:

let letter =Discord.Util.parseEmoji(award[i]).name;
OR
let letter =Discord.Util.parseEmoji(award[i]);

Please find working snippit below:

const a = undefined;

console.log(a);
console.log(a || '');

I don't know exactly, what this little code snippet is aimed to do.. But may this could help you?

let letter = Discord.Util.parseEmoji(award[i]).name.split("_")[1];
if (letter == undefined) {
   return '<:b_:682865394637078531>';
}
if(data.memberData.workStreak > i){
    award[i] = ":regional_indicator_"+letter+":";
}
