using-pool

An object pool library using modern Typescript for auto-recycling.

It takes advatage of the using keyword to recycle the object as soon as it leaves the scope.

const userPool = new Pool(() => ({/** an object factory */}))

function doSomething() {
    using user = userPool.get()

    // do some work with the object
    // (...)

} // as soon as it leaves the scope, `user` is recycled (comes back to the pool to be reused)
