In this topic, we will discuss String localeCompare() in Typescript.

This method returns a number indicating whether a reference string comes before or after or is the same as the given string in sorted order.

Syntax

string.localeCompare( param )

Argument Details

param − A string to be compared with string object.

Return Value

• 0 − If the string matches 100%.
• 1 − no match, and the parameter value comes before the string object’s value in the locale sort order.
• A negative value − no match, and the parameter value comes after the string object’s value in the local sort order.

Example

var str1 = new String( "This is beautiful string" );
  
var index = str1.localeCompare( "This is beautiful string");  

console.log("localeCompare first :" + index );

On compiling, it will generate the same code in JavaScript.

Its output is as follows −

localeCompare first :0
