- Опубликовано: 10 сен 2024
- Welcome, we will see the Default function parameters in JavaScript in Hindi.

However, it's often useful to set a different default value. This is where default parameters can help.
In the past, the general strategy for setting defaults was to test parameter values in the function body and assign a value if they are undefined.
