As @Mathletics suggests, you can disable the rule entirely by adding this to your .eslintrc.json
file:
"rules": {
"no-param-reassign": 0
}
Or you can disable the rule specifically for param properties:
"rules": {
"no-param-reassign": [2, { "props": false }]
}
Alternatively, you can disable the rule for that function:
/* eslint-disable no-param-reassign */
function (el) {
el.expando = {};
}
/* eslint-enable no-param-reassign */
Or for a specific line only:
function (el) {
el.expando = {}; // eslint-disable-line no-param-reassign
}
