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