What do "truthy" values represent in JavaScript?

In JavaScript, "truthy" values are those that evaluate to true when used in a boolean context, such as in conditional statements or logical operations. This means that if a value is considered truthy, it will pass checks that expect a true condition. Examples of truthy values include non-zero numbers, non-empty strings, objects, and arrays.

The concept of truthy is particularly important when you deal with logical statements, conditions in if statements, and loops where you may be testing the validity of expressions or variables. Any value that is not one of the defined "falsy" values — such as false, 0, "", null, undefined, and NaN — is considered truthy.

Thus, the identification of truthy values allows developers to understand how JavaScript interprets various data types and values in different contexts, which is essential for writing effective and bug-free code.
