TypeError: func is not a function
Error message
TypeError: func is not a function
What broke
The code attempted to call a variable as a function, but that variable is either undefined or not a function. This often happens when a variable is incorrectly assigned or when a function is not properly imported.
Why it broke
This error occurs because JavaScript expects a callable function but finds a different type of value, such as undefined, null, or an object. It can also happen if the function was not defined in the current scope or was overwritten.
How to fix
To fix this, ensure that the variable is correctly assigned to a function before calling it. Check for typos in the function name and verify that the function is properly imported or defined in the scope where it's being called.
Code fix
if (typeof func === 'function') { func(); } else { console.error('func is not a function'); }Explained by ErrorOracle
Prevention tip
Check for typos in the function name and verify that the function is properly imported or defined in the scope where it's being called.
