How to import a variable from an event

Question

sugestion.on('collect', a => {
 const Suggestion = a.content;
});
console.log(`Suggestion: ${Suggestion}`);

I'm with TypeError with the above code.

(node:4872) UnhandledPromiseRejectionWarning: ReferenceError: Suggestion is not defined

Answer 1

You are trying to reference a variable out of scope. The variable Suggestion only exists within the scope of the function (a=>{}). Either move the console.log line into the function, or save the value in another variable outside the scope, for future reference.

Answer 2

You need to have the Suggestion variable in scope

let Suggestion;
sugestion.on('collect', a => {
 Suggestion = a.content;
});
console.log(`Suggestion: ${Suggestion}`);
