JavaScript Remove all '+' from array wherein every element is preceded by a + sign

Javascript Web Development Object Oriented Programming

Let’s say the following is our array with elements preceded by a + sign −

var studentNames =
[
   '+John Smith',
   '+David Miller',
   '+Carol Taylor',
   '+John Doe',
   '+Adam Smith'
];

To remove the + sign, the code is as follows −

Example

studentNames =
[
   '+John Smith',
   '+David Miller',
   '+Carol Taylor',
   '+John Doe',
   '+Adam Smith'
];
console.log("The actual array=");
console.log(studentNames);
studentNames = studentNames.map(function (value) {
   return value.replace('+', '');
});
console.log("After removing the + symbol, The result is=");
console.log(studentNames);

To run the above program, you need to use the following command −

node fileName.js.

Here my file name is demo205.js.

Output

This will produce the following output −

PS C:\Users\Amit\javascript-code> node demo205.js
The actual array=
[
   '+John Smith',
   '+David Miller',
   '+Carol Taylor',
   '+John Doe',
   '+Adam Smith'
]
After removing the + symbol, The result is=
[
   'John Smith',
   'David Miller',
   'Carol Taylor',
   'John Doe',
   'Adam Smith'
]
