Semicolons

[goatslacker]

FYI if you're on ES6 then you can't start lines with the template literal syntax either, so that needs to be preceded by a semicolon.

// bad
`hello${world}`

// good
;`hello${world}`

This is because if an identifier precedes the statement then the parser will parse it as a tagged template.

foo

`trololol`

is the same as

foo`trololol`

Thanks for the feedback.

We no longer recommend starting lines with semicolons. It's hacky. Start lines with void, var, const or something that makes more sense. Starting lines with e.g. (, [, or ` is always avoidable. See also #78 (comment)

This issue still applies to this section in particular:

If you're using ES6 then templates are a gotcha too.

@goatslacker could you submit a test to clearly outline this?

I can't imagine a scenario where a line starts with a template string, or any of these other gotchas:

+ * / - ` , . 

But the readme and standard should discourage these explicitly from the start of the line. [ and ( I'm not so sure about, but I'll open another issue.

I don't mean to talk about scenarios where you would start a line with any particular character. I think starting lines with any character that fails ASI is poor style anyway.

I'm just pointing this out.
