Shehzad HussainToday we will see the most important array methods when developing front-end software. They are the most used array methods in my experience.
It is important to be very clear about how they work to develop software quickly and efficiently in our day-to-day since we work a lot with arrays.
Most people need help understanding them, and they always have to go and recheck their operation and spend extra time on it.
5 top array methods
The 5 array methods we are going to talk about are:
**forEach
map
filter
find
slice**
Let's go!
forEach
It executes a provided function once for each array element.
map
It's the method most used when developing with React, as it renders lists of JSX elements.
This method creates a new array in which each element results from the function applied to each one.
filter
It creates a shallow copy of the array, filtered down to just the elements that pass the test implemented by the provided function.
find
It returns the first element in the array that satisfies the testing function.
slice
It returns a shallow copy of the array filtered down to just the elements selected from start to end (end not included), where start and end represent the index of items in that array.
Conclusion
We have already seen the 5 most used methods, and it is crucial to be clear and have skill and experience with them to develop more efficient software in our daily work.
I have chosen these 5 methods based on my experience. You can check out this website and search for each one to find more information about them:
