The every()
method of TypedArray
instances tests whether all elements in the typed array pass the test implemented by the provided function. It returns a Boolean value. This method has the same algorithm as Array.prototype.every()
.

Try it
Syntax
every(callbackFn)
every(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
true
unless callbackFn
returns a falsy value for a typed array element, in which case false
is immediately returned.
Description
See Array.prototype.every()
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 all elements in the typed array are 10 or bigger.
function isBigEnough(element, index, array) {
return element >= 10;
}
new Uint8Array([12, 5, 8, 130, 44]).every(isBigEnough); // false
new Uint8Array([12, 54, 18, 130, 44]).every(isBigEnough); // true
