jspm不会将代码从ES6转换为ES5

Question

Running jspm bundle-sfx some/input some/output.js does not transpile my code from ES6 to ES5. This makes the output file unusable.

Example contents of input file:

[1,2,3,4].map((i)=>i*i);

Answer 1

As explained by jspm author here :

ES6 transpilation only happens for ES6 modules, not ES6 files written in CommonJS.

It means that transpilation happens only for files using module syntax ( import , export ). It can be forced though by adding "format es6"; at the top of the source file as so:

"format es6";
[1,2,3,4].map((i)=>i*i);
