Exploring the concept of lazy loading in typescript, the author provides an example in this section of their book. They demonstrate it using the following piece of code:
import bar = require('bar');
export function loadBar() {
// Lazy loading `bar` and using the original module only for type annotation
var _bar: typeof bar = require('bar');
// Utilizing `_bar` as a variable instead of `bar`.
}
The author explains that when using typescript, the type of 'bar' is only loaded upon first invocation of 'require', whereas the entire module is loaded on the second call when creating the 'bar' variable.
If you're curious about how exactly this mechanism works, could anyone provide a more elaborate example or delve deeper into what's happening behind the scenes?
