i have two arrays and i want to verify to synchronic both, if in both existe the same name that should be stored in the array and the others no
for example: i need all the objects with name rea.jpg but in my array i have like this ['dsjajdsj...h2/rea.jpg']
this is the materials
[{name: 'hgb.jpg' }, { name: 'rea.jpg'}, { name: 'ca.png' }]
the file extension is always the end of the string
i want to verify if exist an object in the names's array
const names = ['h2/rea.jpg']
const materials = [{
name: 'hgb.jpg'
}, {
name: 'rea.jpg'
}, {
name: 'ca.png'
}]
const res = materials.filter(x => names.includes(x.name))
console.log('RES', res)expected result shoud be [ {name: 'rea.jpg'}]
const names = ['h2/rea.jpg']
const materials = [{
name: 'hgb.jpg'
}, {
name: 'rea.jpg'
}, {
name: 'ca.png'
}]
const res = materials.filter(x => {
const ni = names.filter(ni => ni.includes(x.name))
return ni.length > 0
})
console.log(res)
But if names is long and you don't want to iterate over it on every element of materials follow the other suggestion and transform names to only include the filename.
const fnames = names.map(ni => ni.split('/')[ni.split('/').length-1])
const res = materials.filter(x => names.includes(x.name))
console.log(res)
Use some inside of the filter to acheive this (note, this will run in O(n^2)).
const names = ['h2/rea.jpg']
const materials = [{
name: 'hgb.jpg'
}, {
name: 'rea.jpg'
}, {
name: 'ca.png'
}]
const res = materials.filter(x => names.some(y => y.endsWith('/' + x.name)))
console.log('RES', res)Assuming this is Node.js, you can use the path library to convert the fully-qualified pathnames to simple filenames, then do your includes test. For example:
const path = require('path');
const pathnames = ['h2/rea.jpg'];
const filenames = pathnames.map((x) => path.basename(x));
const materials = [
{
name: 'hgb.jpg',
},
{
name: 'rea.jpg',
},
{
name: 'ca.png',
},
];
const res = materials.filter((x) => filenames.includes(x.name));
console.log('RES', res);
// RES [ { name: 'rea.jpg' } ]
