## 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);
