The for loop inside the objToQueryString function showing me the error
ESLint: The body of a for-in should be wrapped in an if statement to filter unwanted properties from the prototype.(guard-for-in)
const objToQueryString = obj => {
const keyValuePairs = [];
for (const key in obj) {
keyValuePairs.push(
`${encodeURIComponent(key)}${encodeURIComponent(
`: "`
)}${encodeURIComponent(obj[key])}`
);
}
return `${encodeURIComponent(`{`)}${keyValuePairs.join(
encodeURIComponent(`", `)
)}${encodeURIComponent(`" }`)}`;
};
And adding this: // eslint-disable-next-line guard-for-in is not working
Wrap your push statement with
const objToQueryString = (obj) => {
const keyValuePairs = [];
for (const key in obj) {
if (Object.prototype.hasOwnProperty.call(obj, key)) {
keyValuePairs.push(
`${encodeURIComponent(key)}${encodeURIComponent(
': "',
)}${encodeURIComponent(obj[key])}`,
);
}
}
return `${encodeURIComponent('{')}${keyValuePairs.join(
encodeURIComponent('", '),
)}${encodeURIComponent('" }')}`;
};
