Javascript remove backslash escape from a string using replace()

The replace() method in javascript will look for a particular pattern in the calling string and replace it with a replacement. The pattern is the first argument and can be a regular expression. The replacement is the second argument. 

Example:-

Remove all the escape characters from the string “This-\\Is-\\\\Dummy\\String\\\\\\\\”

Code:-

let dummyString =  "This-\\Is-\\\\Dummy\\String\\\\\\\\"
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 backslash escape in the string
• g specifies to replace all occurrences.

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

Output:-

This-Is-DummyString

Javascript remove backslash escape from a string using replaceAll()

The replaceAll() method in javascript will replace all the occurrences of a particular character/string in the calling string with a replacement. The character/string is the first argument. The replacement is the second argument.

Example:-

Remove all the escape characters from the string “This-\\Is-\\\\Dummy\\String\\\\\\\\”

Code:-

let dummyString =  "This-\\Is-\\\\Dummy\\String\\\\\\\\"
dummyString =  dummyString.replaceAll("\\", '') 
console.log( dummyString)

Explanation:-

The replaceAll() method is used to find the double quotes (\\) passed in as the first argument and replace all its occurrences with (”) passed as the second argument.

Output:-

This-Is-DummyString

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 the escape characters from the string “This-\\Is-\\\\Dummy\\String\\\\\\\\”

Code:-

let dummyString =  "This-\\Is-\\\\Dummy\\String\\\\\\\\"
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 backslash escape (\\). Finally, using the join() method, these array elements are joined back to form a string without double-quotes.

Output:-

This-Is-DummyString
