Execute the sequence of elements within the provided array repeatedly

As I work on developing a filter, I am faced with an array containing dynamic values that need to be filtered. Despite being one step away from completing the filter, I am struggling with getting the right loop done. I have attempted using forEach without success. Here is the code snippet:

map(p => (!this.personTypeFilter) ? p:p.filter(((i:any) => this.getPersonTypesBezeichnung(i.personentyp)?.toLowerCase().includes(this.personTypeFilter.forEach((x:any) => { return console.log(this.personTypeFilter[x])))))
This current approach causes my code to break down, so I need to find a way to include all values in the filter step by step, possibly utilizing a for loop.

//EDIT

The main objective here is to filter an entire array based on multiple checkboxes which are selected and added to a list. My initial attempt was to loop through each checkbox value using forEach, but it turns out that map is actually the correct solution.

Answer №1

Instead of using a complicated for loop or forEach, you can simplify things by utilizing a map function. Just treat it like a regular for loop - the map function will iterate through all elements in your array as shown below.

map(p => (!this.personTypeFilter.map((x:any) => x)) ? p:p.filter(((i:any) => this.getPersonTypesBezeichnung(i.personentyp).includes(this.personTypeFilter.map((x:any) => x).join(', '))))),
