I have this array whose length could be any number but not less than 4. How do I loop through this array to get a new array that has a length not greater than 4? I tried using the filter method but it returned an empty array.
This is my attempt:
// array could be of any length but not less than 4.
const projects = [
'landing page',
'portfolio page',
'e-commerce app',
'Dapps',
'signup page',
// ... even more
];
const newProjects = projects.filter((project, index, array) => {
return project[index <= 4]
})
console.log(newProjects);Corrected your approach;
const projects = ['landing page', 'portfolio page', 'e-commerce app', 'Dapps', 'signup page',.....] // array could be of any length but not less than 4
const newProjects = projects.filter((project, index, array) => {
return index < 4;
})
console.log(newProjects);
Keep in mind that Array has zero-based index.
Proposed solution:
const newProjects = projects.slice(0,3);
