JavaScript: Short Circuit Evaluation

preview_player
Показать описание
In JavaScript, the short-circuit evaluation is a technique that allows a programmer to use the logical operators && (AND) and || (OR) to test for multiple conditions in a single statement.
When the && operator is used, the expression on the right-hand side is only evaluated if the expression on the left-hand side is true.
When the || operator is used, the expression on the right-hand side is only evaluated if the expression on the left-hand side is false.

Short-circuit evaluation can be useful when you want to test for multiple conditions in a single statement and you want to avoid unnecessary evaluations. It can also make your code more concise and easier to read.
