Lodash is a JavaScript library that provides utility functions for common programming tasks. It can be used to find a key in a nested JavaScript object.
The _.get() function can be used to traverse the object and return the value of the key. It takes three arguments: the object, the path of the key, and a default value.
Example
const data = {
a: {
b: {
c: 'foo'
}
}
};
const value = _.get(data, 'a.b.c', 'default');
console.log(value);
// Output: 'foo'
In the example above, data is the object, 'a.b.c' is the path of the key, and 'default' is the default value. The _.get() function will return the value of the key 'c', which is 'foo'.
The _.get() function is useful for finding a key in a nested JavaScript object.
Parts of code:
const data = { ... }: this is the object containing the nested keysconst value = _.get(data, 'a.b.c', 'default'): this is the_.get()function call, which takes the object, the path of the key, and a default valueconsole.log(value): this logs the value of the key to the console
