Sticky Regex Transpiler

Build a helper that emits source compatible with runtimes lacking sticky regex support by running a transform that rewrites sticky regex literals into RegExp constructor calls with string-literal pattern and flag arguments.

Capabilities

Converts sticky regex literals

• Source const r = /foo/y; export default r.test("foofoo"); is transformed to code that uses new RegExp("foo", "y") in place of the literal while keeping surrounding code intact. @test

Preserves other flags on sticky regex

• Source const r = /f.o/my; r.exec("f\no"); yields a constructor call whose flag string still includes both multiline and sticky semantics. @test

Leaves non-sticky regex unchanged

• Source containing const plain = /bar/g; remains the same literal after transformation. @test

Implementation

API

export function transformStickyRegex(sourceCode: string): string;

The function accepts JavaScript source code and returns the transformed source text.
