I have Object below which I need to convert into below object format but can its possible to do that?
products = {
color: 'red',
type: '2',
status: 'true'
}
converted object
const filters = {
color: color => color === 'red',
type: type => type === '2' ,
status: status => status === 'true',
};
You can do this type of operation:
let products = {
color: 'red',
type: '2',
status: 'true'
};
let filters = {};
Object.entries(products).forEach(e => {
filters[e[0]] = f => f === products[e[0]];
});
Where filters is the object you expect.
Object.entries() when you only use the key part?You can grab the product object's entires using Object.entries():
[["color", "red"], ["type", "2"], ["status", "true"]]
Once you have the entries, you can map over each inner array (ie: each key-value pair) using .map(). For each inner array, you can use destructuring assignment ([key, value]) => to extract both the first and second elements (ie: the key and the value) from the inner array. You can then return a new array, which contains your key in the first index, and a function as a value that checks for equality against the current value and the input argument to the function:
[
[ "color", arg => arg === val ],
[ "type", arg => arg === val ],
[ "status", arg => arg === val ]
]
The above inner arrays are still in the form of [key, value]. As this is the case, you can use Object.fromEntries() on the above array to convert it into an. object:
const products = { color: 'red', type: '2', status: 'true' };
const filters = Object.fromEntries(Object.entries(products).map(([key, val]) => [
key, arg => arg === val
]));
console.log(res);The argument name doesn't match the name of the key, but that shouldn't matter as the argument is a variable
You could loop over using Object.entries(), and add the comparison functions to the filters object.
Here is a working snippet, along with some test cases:
const products = {
color: 'red',
type: '2',
status: 'true'
};
let filters = {};
for (const [k, v] of Object.entries(products)) {
filters[k] = k => k === v;
}
console.log(filters);
console.log(filters['color']('red'));
console.log(filters['color']('blue'));
console.log(filters['type']('2'));
console.log(filters['type']('1'));
console.log(filters['status']('true'));
console.log(filters['status']('false'));
