I'm looking to see if an array has one or more values inside it. For instance, something like so:
[1,2,3,4,5,6].include?([4,1]) # => true [4,1,6,2].include?([4,1]) # => true [3,4,7].include?([4,1]) # => false Of course, the "include?" method can only check one value. Is there a method to check for multiple values?

includes() You can use the includes() method in JavaScript to check if an item exists in an array. You can also use it to check if a substring exists within a string. It returns true if the item is found in the array/string and false if the item doesn't exist.
The some() method tests whether at least one element in the array passes the test implemented by the provided function. It returns true if, in the array, it finds an element for which the provided function returns true; otherwise it returns false. It doesn't modify the array.
Use the includes() method to check if an array contains a value in TypeScript, e.g. if (arr. includes('two')) {} . The includes method will return true if the value is contained in the array and false otherwise. Copied!
