1. Introduction

In this web page there is one web browser JavaScript feature support test: a feature implementation test. The implementation test determines if the web browser recognizes the JavaScript spread operator in Math object methods. The implementation test is a simple test for the presence of web browser support, and a definitive test for the absence of web browser support. If the web browser does not recognize the JavaScript spread operator in Math object methods, the implementation test reports: Fail (no support): The web browser does not recognize the JavaScript spread operator in Math object methods. The web browser does not support the JavaScript spread operator in Math object methods. If the web browser recognizes the JavaScript spread operator in Math object methods, the implementation test reports: Pass (at least partial/possibly full support): The web browser recognizes the JavaScript spread operator in Math object methods. The web browser at least partially/possibly fully supports the JavaScript spread operator in Math object methods. Positive determination of full web browser support is beyond the scope of this test.

The web browser support test source code is shown in Section 2.1. The web browser support test source code is run in Section 2.2, which shows the web browser support test result.

1.1. Spread Operator In Math Object Methods Web Browser Support

  • Pass (at least partial/possibly full support): ED12+, FF27+, CH46+, OP33+.
  • Fail (no support): IE11-, SF5.1.7-.

1.2. Abbreviations

  • IE = Internet Explorer.
  • ED = Edge = EdgeHTML rendering engine (ED12+) and/or Edge browser (ED20+).
  • FF = Firefox.
  • SF = Safari.
  • CH = Chrome.
  • OP = Opera.

2. Spread Operator In Math Object Methods Web Browser Support Test

2.1. Web Browser Support Test Source Code

<p id='testId'><b>Fail</b> (no support): The web browser does not recognize the JavaScript spread operator in <code>Math</code> object methods. The web browser does not support the JavaScript spread operator in <code>Math</code> object methods.</p><!-- Hard code Fail because web browser no support error stops JavaScript execution. -->

<script>
var array = [2, 3, 1];
var arrayMinValue = Math.min(...array);
var arrayMaxValue = Math.max(...array);
if ((arrayMinValue === 1) && (arrayMaxValue === 3)){
 var element = document.getElementById("testId");
 element.innerHTML = "<b>Pass</b> (at least partial/possibly full support): The web browser recognizes the JavaScript spread operator in <code>Math</code> object methods. The web browser at least partially/possibly fully supports the JavaScript spread operator in <code>Math</code> object methods. Positive determination of full web browser support is beyond the scope of this test.";
}
</script>

2.2. Web Browser Support Test Result

Fail (no support): The web browser does not recognize the JavaScript spread operator in Math object methods. The web browser does not support the JavaScript spread operator in Math object methods.
