Swap out the traditional for loop with a LINQ query utilizing the any method

In my TypeScript code, I have the following snippet:

public executeTest(test: Test): void {
    const testFilters: Record<string> = getTestFilters();
    let isTestingRequired: boolean = false;
    
    for (let i: number = 0; i < testFilters.length; i++) {
        if(test.Name === testFilters[i].Name){
            isTestingRequired = true;
            break;
        }
    }
}

I attempted to replace the above for loop with LINQ as shown below, but encountered errors.

let isTestingRequired: boolean = testFilters.any((filter.): boolean => {
    return filter.Name  === test.Name 
});

To make your array iterable, you first need to use Enumerable.from() like so:

var array = [{name: "John"}, {name: "Test"}];

var result = Enumerable.from(array)
  .any(obj => obj.name == "Test");

console.log(result)
