SignalFromSpace - JavascriptModule0

// Signal from Space
// One day a signal from space was registered. Scientists managed to record the signal as a sequence of N symbols. It turned out that due to a technical difficulty some symbols have been repeated. Help the scientists by writing a program which removes consecutive repetitions of symbols, decoding the message.

// Input
// Input data is read from the standard input

// On the only input line, a message is given
// Output
// Print to the standard output

// Print the decoded message
// Constraints
// The length of the message will be no more than 10000 symbols
// Message consists of digits and Latin letters (upper and lower case)
// Sample tests
// Input
// Hello
// Output
// Helo
// Input
// hoboobbo422222Aaao
// Output
// hobobo42Aao
const input = ['Helloo'];
const print = this.print || console.log;
const gets = this.gets || ((arr, index) => () => arr[index++])(input, 0);
const initialSignalLength = gets();
let translatedSignal = '';
for (let i = 0; i < initialSignalLength.length; i++) {
  if (initialSignalLength[i] !== initialSignalLength[i + 1]) {
    translatedSignal += initialSignalLength[i];
  } else {
    continue;
  }
}
print(translatedSignal);
