How to shorten conditional statements with JavaScript?

To shorten conditional statements with JavaScript, we can use the array includes method.

For instance, instead of writing

if (test.type == 1 || test.type == 2 || test.type == 3 || test.type == 4) {
  // do something.
}

We can shorten that to

if ([1, 2, 3, 4].includes(test.type)) {
  // do something
}

We check if at least one of 1, 2, 3, and 4 are set as the value of test.type with

test.type == 1 || test.type == 2 || test.type == 3 || test.type == 4

or

[1, 2, 3, 4].includes(test.type)
