I'm not sure how I feel about these functions. They feel unnecessary to me. If other people want them I might pull them in. Do you have an opinion @johntitus? Also, the underscores in the name irk me, the do not match any of the other function names. |

Regarding underscores - would this sort of syntax be more palatable? .visible('#foo')
.if(function() {
...i.e. add new |
|
I would have just made them |
|
Oh, I see. Cool. I've changed PR to use headlessCamelCase. |
|
Seems useful but I too hesitate to go too far down this sort of rabbit hole. I lean towards accepting this PR (and thanks for making it @aexaey) if tests are added. |
|
Thanks @johntitus , I've added tests and bare-bones descriptions to Readme.md. |

You should just use the existing .exists() action rather than re-implementing it.

Again, you should utilize the existing .visible() action.

Please make the indentation consistent, as I am neurotic about that.

You should pass the resolution value of the previous Promise to fn.
For example
...
.return('foobar')
.ifExists('selectorThatExists', function(res) {
console.log(res); // Should log 'foobar'
