Exactly. It's never about the weight you can lift. It's about the difference between last week's weight and today's. Make progress, be proud of those who make progress.
Such a shitty mindset to laugh about people who started out or might be injured or just can't lift that much or whatever. If they need help, offer help, encourage them, otherwise let them do their thing.
This is likely referring to TypeScript.
TypeScript has all of these patterns, they are used very frequently and they are necessary because TypeScript tends to be interesting from time to time since its types only exist at compile time, because it compiles to JavaScript, which is a language without types.
TypeScript also allows
any
as a keyword, which says "I don't know which type this is and I don't care", which still produces valid JavaScript. To get back to typed variables it is necessary to usetypeof
(or similar constructs like a type guard).https://www.typescriptlang.org/docs/handbook/2/typeof-types.html
