Description

This RFC proposes adding the package symbol/split.

The package should be very similar to the following existing packages:

• symbol/has-instance
• symbol/iterator
• symbol/async-iterator
• symbol/is-concat-spreadable

The primary difference is that the package should export Symbol.split if it exists.

Related Issues

When adding this package, one should do the following:

• copy one of the existing packages mentioned above
• rename the copied package
• find and replace the package name (e.g., has-instance => split)
• find and replace the variable name (e.g., HasInstanceSymbol => SplitSymbol)
• ensure the copyright years are 2025
• update the descriptions according to the symbol's purpose (see MDN)
• update examples to reflect the symbol's purpose (see existing packages for inspiration)
• run tests, benchmarks, and examples to ensure that everything passes
• go back through and check that there are no copy-paste mistakes
