Delete all occurrences of a character in javascript string using replace() and RegEx

The replace() method in javascript will look for a particular pattern in the calling string and replace it with a replacement.

The first argument: is the pattern to be searched for, like a string or a regular expression.
The second argument: is the replacement.

Example:-

Remove all occurrences of ‘-‘ from the string “Javascript- is -popular language”

Code:-

let dummyString = 'Javascript- is -popular language'
dummyString = dummyString.replace(/-/g,'') 
console.log( dummyString )

Explanation:-

The regular expression /-/g is passed as the first argument in the replace() method where,

• / and / mark the beginning and end of the pattern
• – specifies to match the symbol (‘-‘) in the string
• g specifies to replace all occurrences.

The replacement passed as the second argument is (”), which means nothing.

Output:-

Javascript is popular language

Delete all occurrences of a character in javascript string using replaceAll()

The replaceAll() method in javascript replaces all the occurrences of a particular character or string in the calling string.

The first argument: is the character or the string to be searched within the calling string and replaced.
The second argument: is the replacement.

Example:-

Remove all occurrences of ‘-‘ from the string “Javascript- is -popular language”

Code:-

let dummyString = 'Javascript- is -popular language'
dummyString = dummyString.replaceAll('-', '')
console.log( dummyString )

Explanation:-

Here in the above code, the replaceAll() method is used to find the symbol (‘-‘) and replace all its occurrences with (”) passed as the second argument.

Output:-

Javascript is popular language

Javascript remove double quotes from a string using split() and join()

Javascript’s split() method returns an array of substrings formed by splitting a given string.

Javascript’s join() method joins the elements of the array back into a string.

Example:-

Remove all occurrences of ‘-‘ from the string “Javascript- is -popular language”

Code:-

let dummyString = 'Javascript- is -popular language'
dummyString = dummyString.split('-').join('')
console.log( dummyString )

Explanation:-

The above code uses the split() method to split the original string into an array of substrings. The division is done based on a character (-). Finally, using the join() method, these array elements are joined back to form a string. In the resulting string, all occurrences of character (-) are removed.

Output:-

This-Is-DummyString
