I also learnt about pointers in Go.They store the memory address of another variable that can be useful especially when you want to mutate the data or state, it mutates the original data which is performant

Day 4, on Structs
Structs in a data structure in go. Surface to say, they're just like an object in JavaScript where you define the shape or interface of something. You can embed multiple structs in another struct which is straightforward. You can also have a receiver function on them

Now let's talk about retrieving that data from the file system. The "os" has a utility that can be used to get the data "os.ReadFile"
Reading a data from the file system returns the []byte slice and an error

In the slice of todos, since we have a slice of todos in a string type,

to save to the file system. Before that, let's talk about byte slices. So byte slices is the normal slices but with a type of byte which is another data type commonly used to handle binary data. Now in our case, persisting the list of data todos needs to be in a type byte slice. but first,

Day 3 I learned about
1. Reading and writing to the file system
2. Receiver functions
3. Error handling

in slices, there is only way to loop through data which is the `for loop` like this which is straightforward

Day 2: Picking back up where I left off. I covered
1. Variables
2. Slices and Arrays Data types
3. Functions

Day 1
So I started learning go today. I started by installing the go via home-brew. I learn about;
- package main: The package main is the entry point to every go program which compiles the go program into a machine code
