TIL Deallocating memory in Javascript

POSTED ON: Jun 26, 2021

Garbage collection in a nutshell:

Low-level languages require the developer to manually determine at which point in the program the allocated memory is no longer needed and to release it.

Some high-level languages, such as JavaScript, utilize a form of automatic memory management known as garbage collection (GC). The purpose of a garbage collector is to monitor memory allocation and determine when a block of allocated memory is no longer needed and reclaim it.

How do you force garbage collection?

An object is said to be "garbage", or collectible if there are zero references pointing to it.

In other words, set the variable to null.
