checkJs should recognize properties assigned with lodash

Search Terms

js, lodash, properties

Suggestion

Recognize properties of some object when using lodash assign method

Use Cases

Any initalization of an object using:

_.assign(obj, { ...someProps });

// Instead of
this.oneProp = oneProp;
this.anotherProp = anotherProp;

Examples

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

La issue descrive il comportamento di checkJs di TypeScript per le proprietà assegnate tramite il metodo assign di lodash, ma non indica file sorgente, test o punti di ingresso. Inizia riproducendo l’esempio in un test checkJs mirato e traccia il modo in cui vengono riconosciute le assegnazioni di proprietà; il lavoro è completato quando il pattern lodash viene verificato dal type checker senza modificare il JavaScript emesso.
