Searching an array is a common task. In the past we have relied on indexOf and lastIndexOf. As of ES6 there are two new array methods: findIndex and find.

Thanks a lot, the'finIndex' is great. Like you said, 'find' stops as soon as it finds the first match and not the others so a loop is required or can you add a peace of code for it to finish searching the array?
I am bit confused, you say that when using the function in the find method we will return true or false, but then the value is returned. What role does true or false play in that process?
Thank you!
How to compare in lowercase array of string using indexof
Good one!
But if i may ask, what about forEach method?
It can also be used to find a certain value inside of an array. Right?
It will go through each element inside of an array and return the value that we need.
Thanks a lot for this video. Helped a lot. 😊
I love your videos. do you have angular videos of yours in udemy, if yes how much the fee, let me know, please.
Concise and to the point! Do you have a video on comparison of two arrays, finding duplicates, removing them and concatenating them? I am trying to loop over a array that splices itself (poping off duplicate value), obviously this doesnt work. Is it okay to mutate a array or create a new array due to "immutability programming styles"
well done. clear explanation. purchased both of your js courses on udemy after watching this. thanks.
Good explanation
Very good explanation!
