The A to Z of software development notes and how-tos

Me: number + array

JavaScript: Sure, I’ll assume you meant converting them both to strings first? Got it

TypeScript: WTF

[AZ.dev @AZdotDEV]

Few understand this

in JavaScript.

[AZ.dev @AZdotDEV]

TypeScript tip:

If you don't know the type of something, use `unknown` instead of `any`

any basically means I don't care about this type, just let me do anything on it. That's bad

unknown, however, means I don't know this type and I'm not really using it. That's much better

What kind of JavaScript developer are you?

What pattern do you use to name your GraphQL operations?

@rajiths_t @pluralsight Thanks Rajith. Now do the advanced ones 🤓

Learning React or Node today?

Retweet and follow, and I'll DM you a 100% coupon code for my 2 books, React beyond the basics and Node beyond the basics.

Note: The books are still a WIP so any feedback will be greatly appreciated.

Happy Father's Day to all dads and single moms!

If you have to review commits that have mixed whitespace changes, you can use the --color-words diff option to ignore the whitespaces changes.

git diff --color-words

[AZ.dev @AZdotDEV]

Git tip:

Put any non-significant changes that do not affect the code in separate commits.
Examples: trailing whitespaces/eol, code formatting

Don't mix them with other code changes because it makes reviewing a lot harder.

REST is great for resources that are independent of each other.

When you introduce relationships, things become a graph.

Querying a graph with a REST API is like eating a salad one vegetable at a time.

[AZ.dev @AZdotDEV]

@EILYART Definitely. Even if you don’t get to use GraphQL, there is a lot to learn and adapt under REST APIs.

[AZ.dev @AZdotDEV]

Learning GraphQL is learning 2 languages:

The language used by services to describe schemas: object types, scalars, lists, enums, unions, interfaces

The language used by consumers to describe data needs: queries, mutations, subscriptions, fragments, fields, aliases, directives

@waynewallace_io Another giveaway coming soon

[AZ.dev @AZdotDEV]

@TotalSecurily Yep

[AZ.dev @AZdotDEV]

@F_S_Gutierrez Let me see what I can do. Can you please DM your email.

[AZ.dev @AZdotDEV]

“but will this edge case really ever happen?”

YES. And when it does it’ll make your users not trust your app.

Command line tip:

The $_ bash command variable holds the most recent used parameter.

For example, you can:

mkdir ~/some/path

Then:

cd $_

to get into that new directory.

[AZ.dev @AZdotDEV]

@theoutlander Not sure that’s a good strategy. I think frequent small breaks work much better.

[AZ.dev @AZdotDEV]

Coding Tip: When you need to take a long break, or at the end of the day, leave your code in a problem state (red test, error on screen, ...)

This makes it easier for you to resume and remember exactly where you left things off.
