Example 2: javascript test if it is an array

// If you want to test if a variable (object) is an instance of  // an array. You can use the Array.isArray(varName) method // this method takes one argument, the variable or object you want to test // and returns true, if the argument is an array  // or false, if the argument is not an array  if (Array.isArray(object)) { 	// is true } else { 	// is false }  Array.isArray([1, 2, 3, 4]); // Returns true Array.isArray(4); // returns false // this could be used for flattening an array of arrays

Example 3: typeof array

const array = [ 'this', 'is', 'an', 'array' ];   console.log(typeof array); //object
