call-bind reliably determines and securely binds a function's call method, handling edge cases across JavaScript environments. Unlike naive .call.bind(fn), it correctly binds even when fn.call is deliberately non-standard or tampered with. It provides cached, reusable bound call functions for performance and robustly ensures this context is passed as intended, essential for maintaining code integrity and compatibility in diverse JavaScript runtimes. Use callBind(func, receiver, ...args) to invoke func with receiver as this and optional arguments.
