const arryStudent = [{
name: 'faizan',
rollNo: 11,
marks: 80
},
{
name: 'irfan',
rollNo: 12,
marks: 75
},
{
name: 'Abdullah',
rollNo: 13,
marks: 69
},
{
name: 'Asad',
rollNo: 23,
marks: 71
},
{
name: 'ali',
rollNo: 14,
marks: 71
}
];
const startsWithA = arryStudent.filter((student) => student.name.startsWith('A'));
console.log(startsWithA);This is the way you can check..
arryStudent.forEach(element => {
if (element.name[0] == element.name[0].toLowerCase()){
console.log(`${element.name} startswith lower case`);
}
if (element.name[0] == element.name[0].toUpperCase()){
console.log(`${element.name} startswith Upper case`);
}
});
Write a function that filters out the names based on the letter.
const students=[{name:"faizan",rollNo:11,marks:80},{name:"irfan",rollNo:12,marks:75},{name:"Abdullah",rollNo:13,marks:69},{name:"Asad",rollNo:23,marks:71},{name:"ali",rollNo:14,marks:71}];
// Write a function that accepts the data,
// and the letter you're looking for
function find(arr, letter) {
// Always lowercase the letter
const lc = letter.toLowerCase();
// And then filter out the names that match
return arr.filter(student => {
return student
.name
.toLowerCase()
.startsWith(lc);
});
}
console.log(find(students, 'A'));You can use startsWith twice like:
const arryStudent = [{
name: 'faizan',
rollNo: 11,
marks: 80
},
{
name: 'irfan',
rollNo: 12,
marks: 75
},
{
name: 'Abdullah',
rollNo: 13,
marks: 69
},
{
name: 'Asad',
rollNo: 23,
marks: 71
},
{
name: 'ali',
rollNo: 14,
marks: 71
}
];
const startsWithA = arryStudent.filter((student) => student.name.startsWith('A') || student.name.startsWith('a'));
console.log(startsWithA);
