Remove Characters from All Keys in an Object (Lodash OK)

Question

I have a bothersome length of characters before all keys in this object. Since they are all the same, I would like to do a .map() or forEach() or some

Answer 1

You could use the new Object.fromEntries along with Object.entries:

let remove = {
    this: {
        string: {}
    }
}

remove.this.string.a = "apple"
remove.this.string.b = "banana"
remove.this.string.c = "carrot"
remove.this.string.d = "diakon"

console.log(remove.this.string)

let fixed = Object.fromEntries(
    Object.entries(remove.this.string)
        .map(([key, val]) => [key, val])
)

console.log(fixed)

Result: { a: 'apple', b: 'banana', c: 'carrot', d: 'diakon' }

Update:

For keys that are all one string:

let remove = {
    'remove.this.string.a': 'apple',
    'remove.this.string.b': 'banana',
    'remove.this.string.c': 'carrot',
    'remove.this.string.d': 'diakon'
}

let fixed = Object.fromEntries(
    Object.entries(remove)
        .map(([key, val]) => [key.replace('remove.this.string.', ''), val])
)

console.log(fixed)

Result: { a: 'apple', b: 'banana', c: 'carrot', d: 'diakon' }
