I have object which contains array, I want to filter the object based on array value.
For example:
{
"sun":["sleep","walk"],
"mon":["read","dance","ride"],
"tue":["work","dance","sleep"],
}
if I enter keyword "sleep" then result should be as follows
{
"sun":["sleep"],
"tue":["sleep"],
}
Any suggestion would be helpful
Just iterate over the object and do the manipulations, please find working code below:
const obj = {
"sun": ["sleep", 'walk'],
"mon": ["read", "dance", "ride"],
"tue": ["work", "dance", "sleep"],
}
function filterIt(filterString) {
const result = {};
for (const prop in obj) {
if (obj[prop].includes(filterString)) {
result[prop] = [filterString];
}
}
return result;
}
const finalResult = filterIt('sleep');
console.log(finalResult);Useful tools for solving this problem:
let obj =
{
"sun": ["sleep", "walk"],
"mon": ["read", "dance", "ride"],
"tue": ["work", "dance", "sleep"],
};
let result = Object.fromEntries(
Object.entries(obj)
.filter(kvp => kvp[1].includes('sleep'))
.map(([k, v]) => [k, v.filter(o => o === 'sleep')])
)
console.log(result)Using Object.keys, map, includes.
let obj ={
"sun":["sleep","walk"],
"mon":["read","dance","ride"],
"tue":["work","dance","sleep"],
}
let new_obj = {}
let search = 'sleep'
Object.keys(obj).map(key => {
obj[key].includes(search) ? new_obj[key]=[search] : ''
})
console.log(new_obj)
You can use _.transform() to create a new object. Check if the value array (v) includes the str, and if it does assign the key with a new array that includes the str:
const fn = (obj, str) => _.transform(obj, (o, v, k) => {
if(v.includes(str)) o[k] = [str]
})
const obj = {
"sun":["sleep","walk"],
"mon":["read","dance","ride"],
"tue":["work","dance","sleep"],
}
const result = fn(obj, 'sleep')
