'let' not allowed outside strict mode - error

[jywarren]

Travis shows an error in the logs, here:

https://travis-ci.org/publiclab/image-sequencer/jobs/477803581#L830-L834

/home/travis/build/publiclab/image-sequencer/src/ImageSequencer.js:135
    let progressObj, index = 0;
    ^^^
SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode

But it doesn't fail - i'd like to address both issues, getting Travis to actually report a failure in this case, AND then resolving it -- probably with adding strict mode?

Related to #645

GitMate.io thinks possibly related issues are #361 (unreachable code error), #147 (replaceImage() returns error), #537 (Module not found error on demo), #278 (Module not found error in demo), and #145 ("reader is not defined" error on demo).

I would like to work upon it.

Go ahead @Divy123!

@jywarren @tech4GT I tested it by creating a test that uses a simple assignment using 'let' and the test still passed without any errors.
Hence I don't think there is a problem with our image-sequencer code itself.
Also when I went through https://node.green/, it should fail the test.
Would like to know your opinion on this.

Any opinions @jywarren .Also since the tests for node 4 has been removed, I think we can close this issue.
