The some()
method of TypedArray
instances tests whether at least one element in the typed array passes the test implemented by the provided function. It returns true if, in the typed array, it finds an element for which the provided function returns true; otherwise it returns false. It doesn't modify the typed array. This method has the same algorithm as Array.prototype.some()
.

Syntax
some(callbackFn)
some(callbackFn, thisArg)
Parameters
-
callbackFn
-
A function to execute for each element in the typed array. It should return a truthy value to indicate the element passes the test, and a falsy value otherwise. The function is called with the following arguments:
thisArg
Optional-
A value to use as
this
when executingcallbackFn
. See iterative methods.
Return value
false
unless callbackFn
returns a truthy value for a typed array element, in which case true
is immediately returned.
Description
See Array.prototype.some()
for more details. This method is not generic and can only be called on typed array instances.
Examples
Testing size of all typed array elements
The following example tests whether any element in the typed array is bigger than 10.
function isBiggerThan10(element, index, array) {
return element > 10;
}
new Uint8Array([2, 5, 8, 1, 4]).some(isBiggerThan10); // false
new Uint8Array([12, 5, 8, 1, 4]).some(isBiggerThan10); // true
