removeDuplication.ts

import { ICompareFunc } from '../interfaces/Util';

export const removeNonPrimitiveDuplicate = (arr: any[], compareFunc: ICompareFunc) => {
    return arr.reduce((unique, item) => {
        let duplicated: boolean = false;
        for(const key in unique) {
            if (compareFunc(unique[key], item)) {
                duplicated = true;
                break;
            }
        }
        if(!duplicated) {
            unique.push(item);
        }
        duplicated = false;
        return unique;
    }, []);
