Error Handling in Go
by Lane Wagner - Boot.dev co-founder and backend engineer
Go programs express errors with error values. Keep in mind that the way Go handles errors is fairly unique. Most languages treat errors as something special and different. For example, Python raises exception types and JavaScript throws and catches errors. In Go, an error is just another value that we handle like any other value - however we want! There aren't any special keywords for dealing with them.
Go Run vs Go Build vs Go Install
by Lane Wagner - Boot.dev co-founder and backend engineer
go run, go build, and go install compile Go packages for different purposes. go run executes a program without saving the binary in your working directory, go build produces an executable from a main package, and go install installs a compiled command on your machine.
Variables in Go
by Lane Wagner - Boot.dev co-founder and backend engineer
Variables in Go have a type that is known before the code runs. Here's how declarations, type inference, conversions, and scope work.
Switch Statements in Go
by Lane Wagner - Boot.dev co-founder and backend engineer
Switch statements are a way to compare a value against multiple options. They are similar to if-else statements but are more concise and readable when the number of options is more than 2.
Channels in Go
by Lane Wagner - Boot.dev co-founder and backend engineer
Channels are one of Go's core tools for concurrency. They let goroutines communicate with each other, and their blocking behavior helps coordinate work.
If Statements in Go
by Lane Wagner - Boot.dev co-founder and backend engineer
if statements in Go do not use parentheses around the condition.
Functions in Go
by Lane Wagner - Boot.dev co-founder and backend engineer
Functions in Go can take zero or more arguments.
Slices in Go
by Lane Wagner - Boot.dev co-founder and backend engineer
99 times out of 100 you will use a slice instead of an array when working with ordered lists.
String Formatting in Go
by Lane Wagner - Boot.dev co-founder and backend engineer
Go follows the printf tradition from the C language. In my opinion, string formatting/interpolation in Go is less elegant than Python's f-strings, unfortunately.
Structs in Go
by Lane Wagner - Boot.dev co-founder and backend engineer
Structs are one of Go's core tools for organizing related data.
Go Packages vs Modules
by Lane Wagner - Boot.dev co-founder and backend engineer
Packages, modules, and repositories organize Go code at different levels. A package is a directory of code that's compiled together, a module is a collection of packages released together, and a repository can contain one or more modules.
Runes in Go
by Lane Wagner - Boot.dev co-founder and backend engineer
Go's rune type lets you work with Unicode code points that can take more than one byte in a UTF-8 string.
Git Push vs Pull: What's the Difference?
by ThePrimeagen - Ex-Netflix engineer, NeoVim ricer, and Git rebaser
git push sends your local commits to a remote repository. git pull brings remote commits into your current local branch. They move Git history in opposite directions, but pull also integrates what it downloads, which is where the comparison gets interesting.
How to Return Multiple Values in Python
by Lane Wagner - Boot.dev co-founder and backend engineer
A Python function can return more than one value by separating them with commas.
Python / vs //: Floor Division Explained
by Lane Wagner - Boot.dev co-founder and backend engineer
Python's // operator divides and rounds down, so -7 // 3 is -3. See how floor division differs from / and when to use each.
Python Default Parameters: How They Work
by Lane Wagner - Boot.dev co-founder and backend engineer
In Python you can specify a default value for a function parameter. It's useful when a function has parameters that are "optional." You can specify a default value in case the caller doesn't provide one.
Python Break vs Continue: What's the Difference?
by Lane Wagner - Boot.dev co-founder and backend engineer
Sometimes, while looping through a sequence, you may find items that you want to skip. Python provides a way to do this: the continue statement. But what if you want to exit the loop entirely? That's where the break statement comes in.
Python Bitwise AND and OR Operators
by Lane Wagner - Boot.dev co-founder and backend engineer
Bitwise operators are similar to logical operators, but instead of operating on boolean values, they apply the same logic to all the bits in a value by column. The two operators covered here are & (AND) and | (OR).
