Welcome, hasnatali.
When do you expect this code to run?
let response = '' ;
console.log(process.env.MESSAGE_STYLE);
if(process.env.MESSAGE_STYLE==='uppercase'){
// response = "Hello json".toUpperCase();
response = "Hello json".toUpperCase();
}
else{
response = "Hello json";
}
console.log('Bihy',{"style":response})
Also, I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).
