Hi I am new to node js and I am trying to make an array from an object
data.forEach((title) => {
let array = [];
for (var i = 0; i <= data.length; i++) {
array.push(title.title.charAt(0).toUpperCase() + title.title.slice(1))
}
console.log(array);
//access.forEach((conf)=>{
// conf.title
// array
//})
})<script>
let data = [{
title: "user",
fields: "required",
access: "done"
},
{
title: "root",
fields: "default",
access: "done"
},
{
title: "super Admin",
fields: "allready access",
access: "defualt"
},
{
title: "user1",
fields: "required",
access: "done"
},
{
title: "test user",
fields: "required",
access: "done"
},
]
</script>As I want an array which contain all the title in it so I can use that array field inside the access.forEach method but what am getting is title but not in same array but as a different output
expected output
array = [User,Root,Super Admin,User1,Test user]
An arrow function you pass into forEach is executed for every item in the data array so that you create a new array let array=[] for every item of your original one. You either want to declare the array outside of the function:
let array=[];
data.forEach(item => {
array.push(item.title[0].toUpperCase() + item.title.slice(1));
})
or even better use map
let titles = data.map(item => item.title[0].toUpperCase() + item.title.slice(1))
An output in both cases will be:
["User", "Root", "Super Admin", "User1", "Test user"]
You can achieve this by using simple Array.map().
Working Demo :
let data = [{
title: "user",
fields: "required",
access: "done"
}, {
title: "root",
fields: "default",
access: "done"
}, {
title: "super Admin",
fields: "allready access",
access: "defualt"
}, {
title: "user1",
fields: "required",
access: "done"
}, {
title: "test user",
fields: "required",
access: "done"
}];
const array = data.map((obj) => obj.title.charAt(0).toUpperCase() + obj.title.slice(1));
console.log(array);
