log(array1 === array2); // false As you can see, the direct comparison returns false even though both arrays have the same elements. This is because the two arrays are different objects in memory. To compare the elements of the arrays, we need to use other methods. Native Methods for...

Then, you need to create anifblock to check if the array lengths are equal. Only when the length properties are equal will you check on the array values: letarrOne=[1,5,6];letarrTwo=[1,6,5];letresult=false;if(arrOne.length===arrTwo.length){for(leti=0;i<arrOne.length;i++){/...
To compare two JavaScript objects to check if they have the same key-value pairs: Use JSON.stringify() to convert objects into strings and then compare the JSON strings. Use Lodash, a 3rd-party library, isEqual() to perform a deep comparison between the objects. Unlike JavaScript arrays ...
Few things to note though, it won’t work with nested objects and the order of the keys are important. The idea behind this is similar to the stringify way. It coverts the object into a string and compare if the strings are a match. Essentially it's comparing the equality of two ...
