JavaScript Logical connective of values


Example

5.1

.some and .every allow a logical connective of Array values.

While .some combines the return values with OR, .every combines them with AND.

Examples for .some

[false, false].some(function(value) {
  return value;
});
// Result: false

[false, true].some(function(value) {
  return value;
});
// Result: true

[true, true].some(function(value) {
  return value;
});
// Result: true

And examples for .every

[false, false].every(function(value) {
  return value;
});
// Result: false

[false, true].every(function(value) {
  return value;
});
// Result: false

[true, true].every(function(value) {
  return value;
});
// Result: true
