JavaScript Safari - SyntaxError: Unexpected token '>'

Question

I have the problem that this JavaScript snippet runs in Firefox / Chrome without any problem, and Safari I get error: "SyntaxError: Unexpected token '>'".

Here's the code:

window.onclick = (test) => {
  const googleWindow = window.open();
  fakeAjax(response => {
    googleWindow.location.replace(`https://google.com?q=${response}`);
  });
};

function fakeAjax(callback) {
  setTimeout(() => {
    callback('example');
  }, 1);
}

I've googled and have already seen here in the forum, the problem there appears often, unfortunately I have not found a suitable solution.

Thank you in advance Best regards

Solution 1

Arrow function ()=>{} is es6 feature, firefox and chrome both are already supported. But safari old version doesn't. Please check http://kangax.github.io/compat-table/es6/ for more information.

Solution 2

Safari 5.1 is really bad !!!

Example it does not load with =>

var t=w.map(v => String.fromCharCode(v));

Replacement it will take charge

var t=w.map(function(v){return String.fromCharCode(v)});

To make a script work on all browsers, avoid,

1. The => and prefer function () {} instead
2. The function (param = x) {}, prefer function (param) {if (param == 'undefined') {param = x;}}
3. The let and use var instead.
