In TypeScript, the 'target' option is used to specify the ECMAScript version that the TypeScript code will be compiled to. The 'target=ES3' option is now deprecated and will no longer work in TypeScript 5.5.
To silence the error message related to the deprecated 'target' option, you can specify the compiler option 'ignoreDeprecations' in your TypeScript configuration file (tsconfig.json). Set the value of 'ignoreDeprecations' to "5.0" to ignore this specific deprecation warning.
Here's an example of how to configure the 'ignoreDeprecations' compiler option in tsconfig.json:
```json
{
"compilerOptions": {
"target": "es5",
"ignoreDeprecations": "5.0"
}
}
```
By setting the 'ignoreDeprecations' option to "5.0", TypeScript will no longer show the deprecation warning for the 'target=ES3' option. Keep in mind that you should review your code and update the 'target' option to a supported ECMAScript version to take advantage of the latest language features and improvements.
