How To Compare Strings In Javascript?

Similarly, Can I use == to compare strings in JavaScript?

To begin, normal comparison operators === and ==, as well as the utility function Object.is(), are acceptable to use when comparing strings that comprise characters from the Basic Multilangual Plane (including ASCII characters). Because str1 and str2 both contain ASCII characters, comparison operators may be used to securely compare them.

Also, it is asked, How do you compare strings in JavaScript?

Use the localeCompare() function in JavaScript to compare two strings. If both strings are equal, the procedure returns 0; if string 1 is sorted before string 2, it delivers -1; and if string 2 is sorted before string 1, it returns 1.

Secondly, What is == and === in JavaScript?

In JavaScript, the operator = is used to assign values to variables, whereas the operator == is used to compare two variables regardless of their datatype. When comparing two variables, === is used, but this time it will check strict type, which means it will check datatype and compare two values.

Also, Can I use == to compare two strings?

You should not compare these strings using the == (equality operator) since it compares the string’s reference, which determines whether they are the same object or not. The equals() method, on the other hand, examines whether the values of the strings are equal, rather than the object itself.

People also ask, How do you check if strings are equal?

The equals() function compares two strings, returning true if they are equal and false otherwise. To compare two strings lexicographically, use the compareTo() function.
