In TypeScript, you can compare two strings by using the comparison operators such as ==, !=, >, <, >=, <=, or by using the localeCompare() method.
Here are some examples:
### Using Comparison Operators
let str1: string = "hello";
let str2: string = "world";
if (str1 == str2) {
console.log("Strings are equal");
} else {
console.log("Strings are not equal");
}
if (str1 > str2) {
console.log("str1 is greater than str2");
} else {
console.log("str2 is greater than str1");
}
### Using localeCompare() method
let str1: string = "apple";
let str2: string = "banana";
let str3: string = "orange";
console.log(str1.localeCompare(str2)); // returns -1
console.log(str2.localeCompare(str3)); // returns 1
console.log(str1.localeCompare("apple")); // returns 0
In the localeCompare() method, it compares the strings based on the Unicode order and returns -1 if the first string is less than the second string, 1 if the first string is greater than the second string, and 0 if both strings are equal.
