In JavaScript, you can use the try-catch
statement to handle errors that might occur within a block of code. With try-catch
, you can write code to handle the error that occurs, instead of the program coming to a halt and displaying an error message to the user.
To handle multiple errors, simply include multiple catch
blocks after the initial try
block. Each catch
block should handle a specific type of error that might occur. Here's an example:
index.tsx183 chars10 lines
In this example, if an error occurs in the try
block, JavaScript will sequentially check each catch
block to see if it matches the type of error that occurred. If an error matches the type of one of the catch
blocks, the code in that block will be executed to handle the error. If none of the catch
blocks match the error, the error will be thrown outside of the try-catch
statement and the program will halt, displaying the error message to the user.
It's important to note that you shouldn't use catch
blocks to handle all exceptions indiscriminately, as this can hide important errors in your code. Instead, handle only the specific types of errors that are expected to occur in your code.
