space after ArrayBuffer

[tilmannOSG]

@zherczeg There's actually no space needed after ArrayBuffer. Doing a quick "find -name '*.js'|xargs cat|grep new" in jerry-test-suite shows that there is not a single constructor invocation where there is a space before the parentheses.

This patch looks quite good. Please fix the style issues first.

Please update the commit message. Add the related issue number to it. Ex.: "Fixes #1475"

@tilmannOSG hm, you are rgiht. Example 08.01-001.js:

assert(typeof (a) === "undefined");

There is a space after typeof, but there is no space after assert. This is kind of a mixed style, but it is not a good practice.

What shall we do? Let people use whatever they want? These are tests, so perhaps this way we would cover a bigger range of issues.

[tilmannOSG]

@zherczeg I think for now people should just follow whichever style is the most common, e.g. in this case keep the space after the typeof.
In the long-term we can consider adopting one of the common JavaScript coding standards.
I think lexer stress tests should be separate (rather than variations in formatting style), having all the JavaScript tests written in a consistent manner still provides a lot of value :)

LGTM

LGTM

[tilmannOSG]

Please reformat all function/constructor calls to not include a space before the opening parenthesis (this is the formatting used for all the JavaScript source files in JerryScript right now).

[tilmannOSG]

No space between ArrayBuffer and the parentheses please (as discussed previously, seems GitHub lost that feedback).

[tilmannOSG]

Same here: No space between assert and the opening parenthesis please.
