W3Schools Strings Method With Example

/* IN JAVASCRIPT strings are primitve values and they dont have mehthod or properties BUT JS consider stings as objects so we can use mehthod and properties with Srings */ let text = "Hello World Hello"; //returns the lenght of the text console.log(text.length); //extracting the strings from inde console.log(text.slice(2,5)); //extracting the string if its negative then starts from back console.log(text.slice(-1,)); //extractin the string : (from, no of amount to extract); console.log(text.substr(2, 6)); //replace the specific World console.log(text.replace("Hello","Bye")); /* if we have text as >>>>> "Hellow my world you are hello" : text.replace("Hello","bye"); >> will replace only 1st hello : to replace all 'Hello' we use : text.replace("/Hello/g","bye"); */ console.log(text.replace("/Hello/g","bye")); // or we can use console.log(text.replaceAll("Hellow", "bye")); //to upper case console.log(text.toUpperCase()); // to lower case console.log(text.toLowerCase()); // now its time to trim so console.log("TRIMMING " + text.trim()); // adding some before num //if its nume first we need to convet it into strings let padnum = "hey bitch"; let convert = padnum.toString(); let padstart = convert.padStart(10,"o"); console.log(padstart); //SAme you can do with pad end var name = "bhag"; let outputofname = name.padEnd(50," bhai "); console.log(outputofname); //Extracting String Character at specific position console.log(text.charAt(9)); //Extracting String Character code at specific position console.log(text.charCodeAt(9)); // you can also do this console.log(text[9]); //Converting String to arrays var convertedtoarray = text.split(" "); console.log(convertedtoarray[2]);
