Fixed issue with String#dasherize not working on single camel cased letters.Fixed issue with Number.random not recognizing upper limit of 0.Fixed issue with Array#reduce not recognizing 0 as a starting value.

Fixed issue with Array#each/add not allowing negative start indexes.

Fixed issue with omQuery String where floats were not properly being recognized.Fixed issue with Object.isEmpty on non-object types and null.Fixed issue with Object.isEmpty where strings with length > 0 will return true.Array#sortBy now uses these compare methods internally if they exist, so sortBy will get also be able to leverage this advantage. In the next tutorial, we will discuss Array some() method with the help of examples.What is nice about using similarly named methods is that compare methods can then be defined for instances of custom classes, so they can be properly compared as well. Hope that you will have understood how to find the index of the first matching element in an array based on specific test condition using findIndex() method. In this tutorial, you have learned array findIndex() method in JavaScript with the help of example programs. The general syntax of the findIndex() method in JavaScript is: // Arrow functionĪrr.findIndex((element) => ) => name = 'Belly') Let index = numbers.findIndex(isGreater) Ĭonsole.log('Index of first greater number than 2: ' +index) Find the index of first greater number than 2. Callback function to check greater number than 2. Otherwise, it returns -1 if no matching is found.įor example, the following snippet code returns the index of the first number that’s greater than 2. In other words, find() method of array returns the index of first array element that satisfies provided testing function (i.e.
