What is the key to mastering any concept in Angular2 for optimal results?

When creating a Pipe to filter data, I often use the datatype any, allowing for flexibility with types. However, I have some questions regarding this approach:

  • Is it considered a best practice?
  • Does it impact performance when handling large amounts of data?
  • Does it affect application data in terms of variable size?

For instance, consider this example Pipe:

import {Pipe , PipeTransform } from '@angular/core';


@Pipe({
    name:'textFilter'
})
export class TextFilter implements PipeTransform{

transform(data:any,term:any):any{


     if(term===undefined) return data;
     return data.filter(function (da:any) {    
     return da.title.toLowerCase().includes(term.toLowerCase());

     }) 

}

}

In this code snippet, any is used to prevent type mismatches. Is this the recommended approach?

Answer №1

  • Avoiding types is not recommended. Types are meant to assist both you and your fellow developers. If you find them unnecessary, consider using plain JavaScript or the latest ECMAScript versions.
  • Types do not affect performance as they are completely removed at runtime.
  • The presence of types does not impact the compiled output size nor memory usage, since only plain JavaScript code is executed.
