TS2339 error mismatch between tss and tsc about typescript-tools

[clausreinke]

I can run it through tsc 1.5.0-beta without any errors.

I doubt that!-) tsc tends to generate code even in the presence of non-fatal errors, but it does emit the error you mentioned. find is an ES6/2015 method, and tsc/tss default to target ES5, so there has to be an error. Adding --target es6 eliminates the error in both cases.

My mistake. I didn't realize that adding filenames to the tss command line overrode the default behavior of loading the tsconfig.json file. I used the --target ES6 parameter on the command line when testing tsc. At that point I had not yet read this on the typescript wiki:

When input files are specified on the command line, tsconfig.json files are ignored.

Thanks for your explanation.
