Like is-circular
, but returns the path to the first circular reference found.
npm install @cypress/what-is-circular
Returns an array that contains the path to the first circular reference found, or undefined
if no circular reference is found.
var whatIsCircular = require('@cypress/what-is-circular')
var circularObj = {
foo: 1,
bar: 2
}
// qux.baz is the circular reference
circularObj.qux = {
baz: circularObj
}
whatIsCircular(circularObj) // ['qux', 'baz']
var obj = {
foo: 1,
bar: 2,
qux: 3
}
whatIsCircular(obj) // undefined
