In the code snippet below, there are some rows with a nested field value present and some without. I am attempting to assign a value if the field is present, otherwise I want to set it as 'false'. Despite using the double pipe operator to handle this scenario, the code does not execute.
let penetration = result[i].address_stats[1].penetration || false;
I need assistance, please!
Utilize the optional chaining operator:
let penetration = result[i]?.address_stats[1]?.penetration || false;
An alternative approach could be:
let penetration = false;
if ( result
&& result[i]
&& result[i].address_stats
&& result[i].address_stats[1]
&& result[i].address_stats[1].penetration ) {
penetration = result[i].address_stats[1].penetration;
}
Although not all checks may be required, I included them for thoroughness as the structure of result is unknown.
let penetrationValue = false;
if (!result[i].address_stats[1].penetration) {
penetrationValue = result[i].address_stats[1].penetration;
}
// Alternatively
penetrationValue = result[i].address_stats[1].penetration ? result[i].address_stats[1].penetration : false;
