Where developers & technologists share private knowledge with coworkersProgramming & related technical career opportunitiesAdded brackets to make clear that its an expression, while omitting them would work here, it wouldnt work with object destructuring ,This solution worked for me on this context. So you should file an issue on the Eslint github repo to ask about why that line is triggering the "prefer-destructuring" warning.Destructuring is a method of extracting multiple values from data stored in (possibly nested) objects and Arrays. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under Rule Details.

We will go through some examples of how to use destructuring:There are two parties involved in any destructuringThe destructuring target is either one of three patterns:This means you can nest patterns, arbitrarily deeply:Object patterns coerce destructuring sources to objects before accessing properties. The first object parameter determines what types of destructuring the rule applies to.Alternatively, you can use separate configurations for different assignment types. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under /* eslint prefer-destructuring: ["error", {AssignmentExpression: {array: true}}] */ [bar] = array; When Not To Use It If you want to be able to access array indices or object properties directly, you can either configure the rule to your tastes or disable the rule entirely. Prefer destructuring from arrays and objects (prefer-destructuring) With JavaScript ES6, a new syntax was added for creating variables from an array index or object property, called destructuring. This rule takes two sets of configuration objects. Array-destructuring throws a TypeError if the value to be destructured isn't iterableThanks for contributing an answer to Stack Overflow! /* eslint prefer-destructuring: ["error", {AssignmentExpression: {array: true}}] */ [bar] = array; 何时不使用它 如果您希望能够直接访问数组索引或对象属性，则可以将规则配置为您的口味或完全禁用该规则。 Stack Overflow for Teams is a private, secure spot for you and 该规则有两个配置对象。第一个对象参数决定了该规则要应用的解构类型。 The two properties, array and object, can be used to turn on or off the destructuring requirement fo… Beside of the given destructuring assignments, you could take an object destructuring for an array if you like to take certain elements, like the 11th and 15th element of an array.

By using our site, you acknowledge that you have read and understand our I would argue (with the eslint devs) that the rule shouldn't apply to cases where the array value is being assigned to an object property like Ooh that's awesome! In this case, you need to use the object property assignment pattern [YDKJS: ES6 & Beyond] with a new variable name, because you can not have variables as numbers. Featured on Meta Free 30 Day Trial Where developers & technologists share private knowledge with coworkersProgramming & related technical career opportunitiesFWIW, if you don't need a value from an array, when destructuring, you don't need the I've done this: [this.message] = res.response.data.errors[0]; Still giving me same errorHmm that's interesting @Amadan. Therefore, you can Array-destructure any value that is iterable.A value is iterable if it has a method whose key is symbol.iterator that returns an object. Free 30 Day Trial ). This rule takes two sets of configuration objects. I also don't like forcing destructuring of arrays, not because something specific - it just not feels good to me, or at least not always. Please provide me a concept on this.

This rule enforces usage of destructuring instead of accessing a property through a member expression. Why is this necessary? That means that it works with primitive values. It accepts 2 other keys instead of For example, the following configuration enforces only object destructuring, but not array destructuring:For example, the following configuration enforces object destructuring in variable declarations and enforces array destructuring in assignment expressions.If you want to be able to access array indices or object properties directly, you can either configure the rule to your tastes or disable the rule entirely.Additionally, if you intend to access large array indices directly, like:If you want to learn more about destructuring, check out the links below:/* eslint prefer-destructuring: ["error", {VariableDeclarator: {object: true}}] *//* eslint prefer-destructuring: ["error", {AssignmentExpression: {array: true}}] */ Can use empty object pattern to check whether a value is coercible to an object as seen here: Array destructuring uses an iterator to get to the elements of a source. The coercion to object is performed using ToObject() which converts primitive values to wrapper objects and leaves objects untouched.

Your code by itself should be fine.
