go
panic: runtime error: index out of range [3] with length 3
Error message
panic: runtime error: index out of range [3] with length 3
What broke
The program tried to access the fourth element of a slice or array that only has three elements. This results in a runtime panic in Go.
Why it broke
In Go, slices and arrays are zero-indexed, meaning the valid indices for a slice of length 3 are 0, 1, and 2. Attempting to access index 3 causes an out-of-range error.
How to fix
To fix this error, ensure that you are accessing indices within the valid range of the slice or array. You can check the length of the slice before accessing its elements.
Code fix
if index < len(slice) { value := slice[index] }Explained by ErrorOracle
Prevention tip
You can check the length of the slice before accessing its elements.
