Syntax error in ajax response '=>'

On iPhone (Safari, Chrome) and on OSX Safari I get the following error in console:

SyntaxError: Unexpected token ‘>’

Pointing to this line:

this.$http.patch('/api/things/' + id, thing, { method: 'PATCH'}).then((response) => {

[LinusBorg]

the example uses ES6 syntax (namely arrow functions), no one is forcing you to use it this way and ES6 is not required to use vue-resource.

Concerning the example, instead of this:

.then((response) => { …

simply do this:

.then( function (response) { …

[LinusBorg]

does it have any implications on how the returned data is handled?

I thought no, but it turns out yes.

• No, the second example should work, because vue-resource binds the callback to this. At least it did last time I used it with a normal function callback. Seems it doesn’t anymore.
• So yes, you have to func the function to the current scope:

.then(function (response) {
 ...
}.bind(this))

… or use a closure.

Arrow functions keep the this context of where they are called automatically, so they kind of do the above for you.
