How to use a for Loop In Javascript
To create an array of partial objects using a for loop, iterate over the original array, destructure the desired properties, and push new objects containing these properties into a result array. This method extracts and collects specific fields efficiently.
Example:
let studentDetails = [
{
name: 'dinesh',
age: 20,
marks: 30,
},
{
name: 'divi',
age: 20,
marks: 60,
},
{
name: 'vignesh',
age: 30,
marks: 80,
}
];
const partialStudentDetails = [];
for (const student of studentDetails) {
partialStudentDetails.push({
name: student.name,
age: student.age,
marks: student.marks
});
}
console.log(partialStudentDetails);
Output
[ { name: 'dinesh', age: 20, marks: 30 }, { name: 'divi', age: 20, marks: 60 }, { name: 'vignesh', age: 30, marks: 80 } ]
