This project maintains the same style as @gaubee/util (providing functional programming style to avoid side effects) and offers common shims. It supports on-demand imports, and for runtimes with native support, there is minimal additional overhead.
- decimal - Decimal arithmetic for precise numerical calculations
- Based on migration from big.js, serving as a drop-in replacement with pure functions and minimal side effects (stringify:toString/valueOf/toJSON)
- Reference: https://github.com/tc39/proposal-decimal
- pipeline - Functional pipeline operations
- Simulates the
|>operator capability through array arrangement - Reference: https://github.com/tc39/proposal-pipeline-operator
- Note: Currently implements basic pipeline operations only. Additional features like parameter position transformation will be improved in future updates
- Simulates the
- promise - Promise extension functions
- Provides Promise.withResolvers method to obtain Promise's resolve and reject functions
- Reference: https://github.com/tc39/proposal-promise-with-resolvers
- set - Set extension functions
- Provides set operation methods: union, intersection, difference, etc.
- Reference: https://github.com/tc39/proposal-set-methods
By default, this project does not modify any native objects. If you need to apply it globally (polyfill), please use applyEffect for installation. For example:
import {
applyEffect,
promise_with_resolvers,
set_difference,
set_intersection,
set_is_disjoint_from,
set_is_subset_of,
set_is_superset_of,
set_symmetric_difference,
set_union,
} from "@gaubee/tc39-shim";
applyEffect(promise_with_resolvers, set_union, set_intersection, set_difference, set_symmetric_difference, set_is_subset_of, set_is_superset_of, set_is_disjoint_from);
