E0150: missing body for statement; a lexical declaration 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 declare a variable with const or let as the body of such a statement:

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

let favoriteFlavor = random.pick(flavors);

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);
}

let favoriteFlavor = random.pick(flavors);

Introduced in quick-lint-js version 0.2.0.
