How can I optimize the retrieval of deeply nested defaults?
At the moment, I'm employing this code snippet to access the bucket value of check_ab and assigning it a default value of 'A', but this approach is impacting readability:
settings: { experiments: { check_ab: { bucket: abvalue = 'A' } = {} } = {} } = {},
Is there a more efficient way to extract and establish secure defaults?
Perhaps consider deconstructing it into multiple lines for improved readability:
function set(settings = {}) {
const { experiments = {} } = settings;
const { check_ab = {} } = experiments;
const abvalue = check_ab.bucket || "A";
}
In a future JavaScript version, you might opt for a more concise approach:
function set(settings) {
const abvalue = settings?.experiments?.check_ab?.bucket || "A";
}
