spread operator javascript

Question

Quiero copiar objeto y cambiar uno de su campo. Algo como esto:

const initialState = {
showTagPanel: false,
};
export default function reducerFoo(state = initialState, action) {
switch(action.type) {
case types.SHOW_TAG_PANEL:
console.log(state);
return {
...state,
showTagPanel: true
};
default:
return state;
}
}

Este código funciona bien, pero eslint me muestra un error

Unexpected token (14:8)
12 |
13 | return {
> 14 | ...state,
| ^
15 | showTagPanel: true
16 | };
17 |

Aquí está mi .eslintrc:

"plugin:import/errors",

Cómo puedo arreglarlo ?

Answer 1

Actualizar a partir de eslint 5.0.0

Fuente: https://eslint.org/docs/5.0.0/user-guide/migrating-to-5.0.0

Agregue ecmaVersion: 2018 a parserOptions en su archivo .eslintrc .

{
"extends": [
"eslint:recommended"
],
"parserOptions": {
"ecmaVersion": 2018,
"sourceType": "module",
"ecmaFeatures": {
"jsx": true,
}
}
}

Respuesta original

Agregue "experimentalObjectRestSpread": true a ecmaFeatures en su archivo .eslintrc .

Ejemplo

{
"extends": [
"eslint:recommended"
],
"parserOptions": {
"ecmaVersion": 6,
"sourceType": "module",
"ecmaFeatures": {
"jsx": true,
"experimentalObjectRestSpread": true
}
}
}
