The two methods can be used in an array
The every() method is used to determine whether or not all of the array's elements satisfy the given condition.
The some() method is used to determine whether at least one element of the array meets the supplied criterion.
The only difference is that the some() function returns true if any of the predicates are true, but the every() method returns true if all of them are true.
The some() method is used in this example.
function isnumbereven(element) {
return (element % 2 == 0);
}
function print() {
var arr = [ 4, 3, 13, 43, 58 ];
// cheking if at least one number is even
var value = arr.some(isnumbereven);
console.log(value);
}
print();
output: true
The every() method is used in this example.
function isnumbereven(element) {
return (element % 2 == 0);
}
function print() {
var arr = [ 4, 3, 13, 43, 58 ];
// cheking if all the number are even
var value = arr.every(isnumbereven);
console.log(value);
}
print();
output: false
