Logical operators

TypeScript supports the following logical operators. To understand the examples, you must assume that variable A holds 10 and variable B holds 20:

Operator	Description	Example
`&&`	Known as the logical `AND` operator. If both the operands are nonzero, then the condition becomes `true`.	(A && B) is true.
`\|\|`	Known as the logical `OR` operator. If any of the two operands are nonzero, then the condition becomes `true`.	(A \|\| B) is true.
`!`	Known as the logical `NOT` operator. It is used to reverse the logical state of its operand. If a condition is `true`, then the logical `NOT` operator will make it `false`.	!(A && B) is false.
