TypeScript Tip #10

I have an array of strings and I’d like to insert a number value there.

How can I do it with TypeScript?

Answer: you need a new array of the union type “string | number”

@WellPaidGeek Looks like the shortage is not big enough

[Tomasz @t_tarnowski]

@WellPaidGeek Rockets run on software like most things nowadays.

I'm not very surprised.

[Tomasz @t_tarnowski]

@TheJackForge Don't you mean "comment out"?

[Tomasz @t_tarnowski]

@saviomartin7 And if you want to outperform everyone else learn TypeScript and the basics of AWS (EC2, S3, Lambda).

@TheAnkurTyagi Great thread, Ankur!

I feel like there's not enough testing-related content on Tech Twitter.

[Tomasz @t_tarnowski]

@DThompsonDev 90% of commercial JavaScript/TypeScript backend work I've done over the past 15 years was working with APIs, REST, and JSON, so yeah I can definitely agree.
