Code Review
This PR adds a new JavaScript quickstart for the Code Execution feature. The implementation is straightforward, but I have a few suggestions to improve it. The most important one is to enhance the response logging to properly demonstrate the code execution feature by showing the generated code and its output, not just the final text summary. I've also suggested a change for consistency in naming conventions and a minor fix for file formatting. Additionally, please remember to update the quickstarts-js/README.md to include this new example in the table of contents for better discoverability.

Simply logging response.text is insufficient for a code execution quickstart, as it only shows the model's final summary. To properly demonstrate the feature, you should parse the response to show the executable code and its output. This gives the user a much clearer understanding of what the Code Execution tool does. The Get_Started.js file provides a good example of this.
// The response includes the model's thought process, the code it ran, and the final answer.
for (const part of response.candidates[0].content.parts) {
if (part.text) {
console.log(part.text);
} else if (part.executableCode) {
console.log('--- Executable Code ---');
console.log(part.executableCode.code);
} else if (part.codeExecutionResult) {
console.log('--- Code Execution Result ---');
console.log(part.codeExecutionResult.output);
}
}

For consistency with other JavaScript quickstarts in this repository, it's better to name this constant MODEL_ID. This makes it easier for users to identify and change the model being used. Please also update its usage on line 33.

It's a good practice to end files with a newline character. This can prevent issues with some tools and file concatenation.

Summary
This PR adds a missing JavaScript quickstart example for the Code Execution feature. Previously, this example was not available in the
quickstarts-jsdirectory.Implementation Details
quickstarts-js/Code_Execution.js.gemini-2.5-flash-lite. This ensures the example runs reliably on the Free Tier without hitting the strict limits of experimental models.codeExecutiontool and correctly parse the response using the@google/genaiSDK.Verification
