Object literal throws parse error

[futurist]

Below code will throw Parse Error:

echo '{a:1, b:2}' | standard --stdin

Throws:

:1:8: Parsing error: Unexpected token :

But it's valid javascript code.

It's important for this issue, since some times a JS file only store data, to feed other JS to read.

Oops, actually its not a valid JavaScript file. It needs to be ({a: 1}) with parenthesis because the curlies will otherwise mean a block statement instead of an object literal. You can try this out with a JavaScript parser demo here: http://esprima.org/demo/parse.html

@rstacruz Nice to know!

@futurist If you're just storing data in a file, you might want to consider using a .json extension instead of .js.

for the record, the same issue seems to arise with object destructuring assignment:

• valid

var { ids, languages, props, format } = obj

• invalid

var ids, languages, props, format
{ ids, languages, props, format } = obj // Parsing error: Unexpected token =

• valid

var ids, languages, props, format
({ ids, languages, props, format }) = obj
