eslint/no-obj-calls Correctness

✅ This rule is turned on by default.

What it does

Disallow calling some global objects as functions

Why is this bad?

Some global objects are not intended to be called as functions. Calling them as functions will usually result in a TypeError being thrown.

Example

Examples of incorrect code for this rule:

let math = Math();
let newMath = new Math();

let json = JSON();
let newJson = new JSON();

let atomics = Atomics();
let newAtomics = new Atomics();

let intl = Intl();
let newIntl = new Intl();

let reflect = Reflect();
let newReflect = new Reflect();

Examples of correct code for this rule:

let area = (r) => 2 * Math.PI * r * r;
let object = JSON.parse("{}");
let first = Atomics.load(sharedArray, 0);
let segmenterFrom = Intl.Segmenter("fr", { granularity: "word" });
