Can I load a large number of JSON files using the Require ('. Json ') method?

The non-blocking I/O is respected in node. js, but require is a synchronous call to a module, which leads to a performance overhead, but not every time require is time consuming because it is cached after the require succeeds and is read directly from the cache when it is loaded, with no additional overhead.

While loading files via. JSON is convenient, it can be cached when used in large numbers. Large amounts of data reside in memory, resulting in frequent GC and memory leaks.
