Truth Table Cheat Sheet

The following table shows the values for some simple boolean expressions.

For example, read it like this (second row): if a is true and b is false, then a || b (a or b) is true.

a	b	`!a`	`a && b`	`a \|\| b`
`true`	`true`	`false`	`true`	`true`
`true`	`false`	`false`	`false`	`true`
`false`	`true`	`true`	`false`	`true`
`false`	`false`	`true`	`false`	`false`
