/**
 * <p>Updates a CloudFront function.</p> <p>You can update a function's code or the comment that describes the function. You cannot update a function's name.</p> <p>To update a function, you provide the function's name and version (<code>ETag</code> value) along with the updated function code. To get the name and version, you can use <code>ListFunctions</code> and <code>DescribeFunction</code>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { CloudFrontClient, UpdateFunctionCommand } from "@aws-sdk/client-cloudfront"; // ES Modules import
 * // const { CloudFrontClient, UpdateFunctionCommand } = require("@aws-sdk/client-cloudfront"); // CommonJS import
 * const client = new CloudFrontClient(config);
 * const input = { // UpdateFunctionRequest
 *   Name: "STRING_VALUE", // required
 *   IfMatch: "STRING_VALUE", // required
 *   FunctionConfig: { // FunctionConfig
 *     Comment: "STRING_VALUE", // required
 *     Runtime: "cloudfront-js-1.0" || "cloudfront-js-2.0", // required
 *     KeyValueStoreAssociations: { // KeyValueStoreAssociations
 *       Quantity: Number("int"), // required
 *       Items: [ // KeyValueStoreAssociationList

 *   FunctionCode: new Uint8Array(), // e.g. Buffer.from("") or new TextEncoder().encode("")   // required
 * };
 * const command = new UpdateFunctionCommand(input);
 * const response = await client.send(command);
 * // { // UpdateFunctionResult
 * //   FunctionSummary: { // FunctionSummary
 * //     Name: "STRING_VALUE", // required
