Are there any equivalents of Python any() and all() functions in JavaScript?
I need methods which can be applied on a list (array) as following:
any()- returnstrueif any element of the iterable istrue. If the iterable is empty, returnsfalse.all()- returnstrueif all elements of the iterable aretrue, or if the iterable is empty.
Are there any equivalent built-in functions available in JavaScript?

You can implement a custom any() and all() methods using simple for loop combined with if statement.
Practical example
1. any() function:
xxxxxxxxxx1
const any = (array) => {2
for (let i = 0; i < array.length; ++i) {3
if (array[i]) return true;4
}5
return false;6
};2. all() function:
xxxxxxxxxx1
const all = (array) => {2
for (let i = 0; i < array.length; ++i) {3
if (!array[i]) return false;4
}5
return true;6
