#51 Golang - Mastering Golang Context: Enhance Concurrency Control

In this episode, we dive deep into the context package in Go, a crucial tool for managing concurrency and ensuring your applications run smoothly. We'll walk you through examples demonstrating how to use context for canceling operations, handling timeouts, and passing values across goroutines. Whether you're new to Go or looking to solidify your understanding, this episode will help you master context and improve your ability to write efficient, responsive, and maintainable code.

What You'll Learn:
- How to create and cancel contexts to control goroutines
- Managing time-sensitive operations with context timeouts
- Understanding the difference between context timeouts and deadlines
- Using context values to pass data across function calls in a type-safe manner

Useful video introducing these concepts, thanks!

[algnadjib]

we have to design the routines in such a way to keep checking the cancellation
jobs that take longer time has to be devided

[algnadjib]

but what happens to the cancelled go-routines that take longer time?
the caller which checks the cancellation seems to exist but the go-routine that does the work seems to continue working !
