E0149: missing body for statement; a class statement is not allowed as the body of statement

do-while loops, if statements, for loops, while loops, and with statements require a statement or list of statements for the body. It is a syntax error to write a class as the body of such a statement:

let flavors = [];
for (let flavor in config.sweets)

class SweetsBasket { /* ... */ }

To fix this error, write the body of the do-while loop, if statements, for loop, while loop, or with statement:

let flavors = [];
for (let flavorName in config.sweets) {
  flavors.push(flavorName);
}

class SweetsBasket { /* ... */ }
