SyntaxError: expecting ';' when returning a simple object

[jeromegn]

An object with a single field appears to return its value, an object with 2 fields fails to compile.

$ qjs -i
QuickJS - Type "\h" for help
qjs > "hello"
"hello"
qjs > {hello: "world"}
"world"
qjs > {hello: "world", foo: 1}
SyntaxError: expecting ';'
    at <evalScript>:1
qjs > {hello: "world", foo: 1};
SyntaxError: expecting ';'
    at <evalScript>:1
qjs > { hello: "world"; foo: 1 }
1

I have noticed the same when using quickjs as a library, but this is the easiest way to show a reproduction.

I don't understand why the last case works, but it appears to be the same issue as the case with a single-field object.

It is the normal behavior i.e. at top level {hello: "word"} is interpreted as a code block with label 'hello'. You must use the syntax:

({hello: "world"})

instead.

Thank you, I could not find that information. It makes sense. I suppose browser-JS-engines just wrap the input in parens when evaluating from the console.
