Hey! I am Currently learning Go Lang, and I am taking some basic Notes on my Notion and though I'd also just publish them here. They are not well thought out or well written but it's just me taking notes from time to time for my reference.

## Notes

### Variable Declarations

* variables can be declared via “var” keyword
    
* and also with special assignment operator “:=” so with that we can remove the “var” keyword
    
* this assignment operator is useful when we dont have to change the type of variable that is assigned by GO
    
* because with “:=” we can not declare the type of variable
    

```go
expectedReturn float64 := 5.5
```

above is invalid

```go
expectedReturn := 5.5
```

above is valid

* we can declare multiple variables at the same time with same type
    

```go
	var investmentAmount, years float64 = 1000, 10
```

* if we dont declare the type of variable on that line then we can also declare multiple variables with different types
    

```go
	var investmentAmount, years  = 1000, "10"
```

I am currently learning Go Lang from a Udemy course and I wan to log my notes so i am sharing them here
