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.
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:
element
- : The current element being processed in the typed array.
index
- : The index of the current element being processed in the typed array.
array
- : The typed array
every()
was called upon.
- : The typed array
- : 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
- : A value to use as
this
when executingcallbackFn
. See iterative methods.
- : A value to use as
Return value
true
unless callbackFn
returns a
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 bigger than 9.
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
