BuckleScript targets ES5.
Below is a list of polyfills from ES6 needed:
Math.imul
This polyfill is needed for int32 multiplication. The polyfill is actually implemented in the generated code.
No action is required by the user.
TypedArray
The following functions require the TypedArray polyfill:
- Int64.float_of_bits
- Int64.bits_of_float
- Int32.float_of_bits
- Int32.bits_of_float
The TypedArray polyfill is not provided by BuckleScript and it's the responsibility of the user to bundle the desired polyfill implementation with the BuckleScript generated code.
For the current BuckleScript version, if the user does not bundle the TypedArray polyfill and the JavaScript engine does not support it, the code will fail at runtime.
