Show me your unnecessary code

Hi. Somehow, I wrote this code piece in the past. Today, I don't use this code but this still exists in our project.

function isNumber(data) {
    return typeof data == 'number' && !isNaN(data)
}

function isBoolean(data) {
    return typeof data === "boolean"
}

function isFloat(data){
    return isNumber(data) && data % 1 !== 0
}

function isNull(data){
    return !data && Object.is(data, null) && data === null
}

function isUndefined(data) {
    return !data && Object.is(data, undefined) && data === undefined
}

function isEmpty(data) {
    return data === "" && data.length === 0
}

const I = {
    sware: {
        this(data) {
            return {
                is: {
                    number: () => isNumber(data),
                    float: () => isFloat(data),
                    bool: () => isBoolean(data),
                    null: () => isNull(data),
                    undefined: () => isUndefined(data),
                    empty: () => isEmpty(data)
                }
            }
        }
    }
}

const aNumericValue = 341
const aFloatValue = 3.14
const aBoolValue = false
const aNullValue = null

You can use this like that;

const aNumericValue = 341
I.sware.this(aNumericValue).is.number()

So, what is yours?
