I am trying to convert a string array into single nested object suggest a best way to do that,
For example, If I had a single element in an array
Input:
var keys = ["A"];
It should be like this,
Output:
{
and: {
tags: {
contains: "A"
}
}
}
And if I add a second element for example,
Input:
var keys = ["A","B"];
It should add as a nested object like this,
Output:
{
and: {
tags: {
contains: "A"
},
and: {
tags: {
contains: "B"
}
}
}
}
You can try to use Array.reduceRight function(Thanks Drew Reese's suggestion):
const nest = arr => arr.reduceRight((acc, cur) => ({ and: { tags: { contains: cur }, ...acc } }), {});
console.log(nest(['A']));
console.log(nest(['A', 'B']));
console.log(nest(['A', 'B', 'C']));
