I wanted to make a program that collects a property from an object and checks if that property matches a character or a word in a given sentence, if true then the program replaces that property with it's corresponding value.
e.g
obj = {
":)" : "🙂",
":(" : "☹️"
}
str = "hello friend :)"
I want my output to be
hello friend 🙂
I have tried solving this but my code returns no output.
please help.
my code [produces no output]

emoji is an object not array so you have to do
if(j == words[i])
edited:
if (j == words[i]) {
words[i] = emoji[j];
}

You are joining the word inside the condition so when condition will match then it will be append in words otherwise not that's why you got only :)

There are many ways to achieve this.
You can also do like this:
for(i in words) {
if (emoji [words[i]]) //it will return true if exist
words[i] = emoji [words[i]];
}
words = words.join(" ")
Another way of using replaceAll method.
Get all the key elements into an array using Object.keys method, then iterate replaceAll method with respected key and value.
You only need this:
Object.keys(emoji).forEach(key => words = words.replaceAll(key, emoji[key]));

I wrote this to answer a friend just the other day. If you comment line 47 and add the emojis to the <sym> object, I think you can have just what you want.
