score:1
you can also do:
handleclick() {
// code here
}
score:6
you get the error because class properties (class example { myproperty = 'foobar' }
) is not a part of the language yet.
you need to add either a babel plugin or preset for it to work. you could use the stage 2 preset.
.babelrc
{
"presets": [
"react",
"env"
"stage-2"
]
}
