You can use the findIndex value like this, which runs a function for each item in the array, which is passed the element, and its index. Returning from it will assign the return value to the return value of findIndex:const letters = [ { letter: 'a', }, { letter: 'b', }, { ...
JavaScript Array Contains: Find an Object There are three common approaches you can take to determine if an object is present in an array. You can use: some find findIndex Some Method Thesome()method returnstrueif any one element in the array satisfies the condition in callback and is pass...
