## 4 Tools for WebAssembly Development
### WebAssembly Standardized Features for Existing Web Browsers and Tools  
* **JS BigInt to Wasm i64 Integration** The initiation for Wasm _BigInt_<->_i64_ conversion in the JS API has been incorporated into the main specification. As a result, BigInt's now have the ability to convert back and forth between 64-bit integer Wasm values. This conversion can be applied to parameters and return values of exported Wasm functions, as well as parameters and return values of host functions. Additionally, _BigInt's_ can be used with imported and exported globals. Reading from or writing to Wasm memory using _BigInt64 Array_ or _BigUint64 Array_, as introduced in the BigInt proposal, can be done without requiring any additional support. * **Bulk Memory Operations** The introduction of Bulk Memory Operations and Conditional Segment Initialization in Wasm addresses specific needs and optimizations related to memory operations and segment initialization. \begin{table}
