+
+Allows you to do sync operation on data. If \`send\` function isn't called the data flow will not continue.
+
+__Custom function__:
+
+\`\`\`javascript
+data;          // received data
+send;          // send data to next component, optionaly specify output index -> send(0, data);
+instance;      // ref to value.instance, available methods get, set, rem for storing temporary data related to this instance of Function component and  debug, status and error for sending data to designer
+global;        // ref to value.global, available methods get, set, rem for storing persistent data globally accessible in any component
+flowdata;      // ref to value.flowdata, instance of FlowData - available methods get, set, rem for storing temporary data related to current flow
+flowdata.data; // user defined data recieved from previous component
+
+// Example:
+send('Hello world.'); // sends data to all outputs
+send(0, 'Hello world.'); // sends data only to first output
+
+// Calling send without any argument will pass incomming data to next components
+send();
