Question

Reversing the order of items in Angular 2 for repetition

Is there a way to display search items in reverse order? This is what I have attempted so far:

 let newSearchTerm = this.getItem(this.searchHistoryKey)
      newSearchTerm.push({
        'q': this.searchTerm
      });

 this.setItem(this.searchHistoryKey, JSON.stringify(newSearchTerm));




<li *ngFor="let search of searchHistory"><span th-icon th-time>icon</span><a href="/"><label for="">{{search.q}}</label></a><span (click)="addHistory()" th-icon arrow-up>icon</span></li>

Any suggestions on how to display the search results in reverse order?

Give this filter a shot:

app.filter('reverse', function() {
  return function(items) {
    return items.slice().reverse();
  };
});

...

*ngFor="let search of searchHistory | reverse"

reverseArray(jsonArray) {
      let reversedArray = [];
      for (let index = jsonArray.length - 1; index >= 0; index--) {
        reversedArray.push(jsonArray[index]);
      }
      return reversedArray;
    }

This solution was very useful, and I implemented it using only plain javascript.
