.chain returns what is directly inside the promise, without doing any additional magic. This is different from .then, which "flattens" promises. For a more concrete example, assume that "x" is a Promise<Promise<integer>>. That is, it's a promise, holding a promise, holding an integer. x.chain(arg=>"arg is a Promise<Integer>"), x.then(arg=>"arg is an Integer"). ~TJ _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
