Mastering the Use of &&, ||, and === in Ternary Operations

Tyler MacDonald Updated by Tyler MacDonald

When working with ternary operations, understanding the proper use of logical and comparison operators is essential. These operators help you construct clear and efficient conditional logic. In this article, we'll delve into the use of &&, ||, and === within ternary operations, providing a comprehensive guide to their correct usage.

Logical Operators: && and ||

Logical operators are used to combine multiple conditions in a ternary operation.

  • && (Logical AND): Returns true if both operands are true. If either operand is false, it returns false.
  • || (Logical OR): Returns true if at least one of the operands is true. If both operands are false, it returns false.
Example of && in a Ternary Operation

Consider a scenario where you want to check if both High_Quality and White_Ink are true to apply a specific action:

(High_Quality && White_Ink) ? applyHighQualityWhiteInk : applyDefault;

In this example:

  • If both High_Quality and White_Ink are true, applyHighQualityWhiteInk is executed.
  • If either High_Quality or White_Ink is false, applyDefault is executed.
Example of || in a Ternary Operation

Now, consider a scenario where you want to check if either High_Quality or White_Ink is true to apply a specific action:

(High_Quality || White_Ink) ? applyEitherHighQualityOrWhiteInk : applyDefault;

In this example:

  • If either High_Quality or White_Ink is true, applyEitherHighQualityOrWhiteInk() is executed.
  • If both High_Quality and White_Ink are false, applyDefault() is executed.

Assignment and Comparison Operators: ===

  • === (Strict Equality Operator): Compares two values for equality without performing type conversion. Both value and type must be the same.
Using === in Ternary Operations

Comparison operator === is used to compare values within the conditional part of a ternary operation.

Example with ===
(Reference_name === 'YourBannerMaterial') ? doSomething: doNothing;

In this example:

  • If Reference_name is exactly equal to the string 'YourBannerMaterial' (no type conversion), doSomething
  • Otherwise, doNothing.

Combining Logical and Comparison Operators

You can combine logical and comparison operators to construct more complex conditions within a ternary operation.

Example:

(value1 === value2 && value3 > value4) ? doSomething : doNothing;

In this example:

  • The condition checks if value1 is strictly equal to value2 and if value3 is greater than value4.
  • If both conditions are true, 'doSomething'.
  • If either condition is false, 'doNothing'.

Understanding the proper use of &&, ||, and === is crucial for constructing effective ternary operations in shopVOX. By mastering these operators, you can write concise and efficient conditional logic that enhances your custom configurations and improves code readability. Use this guide as a reference to ensure you are applying these operators correctly in your ternary operations.
