Congrats!

You’re really raising the bar for tech content. Go Jason. 🔥🚀

awww I grew up listening to some wild jazz from here. May she RIP

Congrats let me be your +1 subscribers 😀

This is a good read.

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

I also got a hung of receiver functions, they're basically like an oop concept, methods defined on that type

the content must be converted from byte slices back to strings.

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,

the slices of todos needs to be converted to string and then to a byte slice before writing to a file

```
os.WriteFile(fileName, []byte(t.toString()), 0666)
```

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,

Writing to the filesystem in go requires the use of the 'os' package which has so many utilities which provides platform related interfaces. Writing to a file uses the syntax `os.WriteFile` which creates and overrides an existing data
In my little todo program, I have slices of todos that I needed

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

3. Functions: Just like in any other programming languages, functions in go is declared with the func keyword with the name and the body

depending on what the function is doing you might need to add a return type

for example a function returning a string should have a return type of string
