8. Using Yocto-RangeFinder with JavaScript /
EcmaScript

EcmaScript is the official name of the standardized version of the web-oriented programming
language commonly referred to as

JavaScript

. This Yoctopuce library take advantages of advanced

features introduced in EcmaScript 2017. It has therefore been named

Library for JavaScript /

EcmaScript 2017

to differentiate it from the previous

Library for JavaScript

, now deprecated in favor

of this new version.

This  library  provides  access  to  Yoctopuce  devices  for  modern  JavaScript  engines.  It  can  be  used
within  a  browser  as  well  as  with  Node.js.  The  library  will  automatically  detect  upon  initialization
whether  the  runtime  environment  is  a  browser  or  a  Node.js  virtual  machine,  and  use  the  most
appropriate system libraries accordingly.

Asynchronous communication with the devices is handled across the whole library using Promise
objects, leveraging the new EcmaScript 2017

async

/

await

non-blocking syntax for asynchronous

I/O (see below). This syntax is now available out-of-the-box in most Javascript engines. No
transpilation is needed: no Babel, no jspm, just plain Javascript. Here is your favorite engines
minimum version needed to run this code. All of them are officially released at the time we write this
document.

• Node.js v7.6 and later
• Firefox 52
• Opera 42 (incl. Android version)
• Chrome 55 (incl. Android version)
• Safari 10.1 (incl. iOS version)
• Android WebView 55
• Google V8 Javascript engine v5.5

If you need backward-compatibility with older releases, you can always run Babel to transpile your
code and the library to older standards, as described a few paragraphs below.

We don't suggest using

jspm 0.17

anymore since that tool is still in Beta after 18 month, and

having to use an extra tool to implement our library is pointless now that

async

/

await

are part of

the standard.

8.1. Blocking I/O versus Asynchronous I/O in JavaScript

JavaScript is single-threaded by design. That means, if a program is actively waiting for the result of
a network-based operation such as reading from a sensor, the whole program is blocked. In browser
environments, this can even completely freeze the user interface. For this reason, the use of blocking
