JavaScript typedArray.some() Method
The typedArray.some() is an inbuilt function in JavaScript which is used to check whether some elements of the typedArray satisfy the test implemented by the given function.
Syntax:
typedarray.some(callback)
Parameters: It takes the parameter callback function and this callback function takes three parameters that are specified below-
- Value: It takes the value of the current elements.
- index: It takes the index of the current element which are being traversed in the typedArray.
- array: It is the required typedArray.
Return value: It returns true if the callback function passes all the elements truly otherwise it returns false.
Example: JavaScript code to show the working of this function.
javascript
function isNegative(element, index, array) {
return element < 0;
}
const A = new Int8Array([-5, 10, -15, 20, -25]);
const B = new Int8Array([5, 10, 15, 20, 25]);
const C = new Int8Array([-10, -20, -30, -40, -50]);
const D = new Int8Array([0, 0, 0, 0]);
console.log(A.some(isNegative));
console.log(B.some(isNegative));
console.log(C.some(isNegative));
console.log(D.some(isNegative));
|
Output:
true
false
true
false
Here the output is true because the typedArray A and C have negative elements, and B and D typedArray have positive elements that is why it gives false as output.
