The usage and difference between some() and filter() in JavaScript arrays (with code)

Now I will bring you an article on the usage and difference between JavaScript array some() and filter(). Now I share it with you and give it as a reference.

some method

array1.some(callbackfn[, thisArg])

For each element in array array1 Call the callback function callbackfn. When the callback function returns true or all arrays are traversed, the some method terminates. The optional parameter thisArg can replace the this object in the callback function

filter method

array1.filter(callbackfn[, thisArg])

Call the callback function callbackfn method on each element in array array1. This method will return a new collection of elements that return true in the callback function. The optional parameter thisArg can replace the this object in the callback function

The difference between the two

Some methods return a boolean value, which can be used Check whether there is an object in the array

The filter method returns a new array, which can be used to filter the objects in the array

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future. .
