How to use

Let's see about js code:

    let jsutil = require('nodejs-coreutils');
    
    let _maskcode=jsutil.maskcodeFixedLength("shivapendemshivapendemshivapendemshivapendemshivapendem","x");  
    console.log(_maskcode);
        //shivxxxxxndem
    
    let _md5=jsutil.getMD5("shivapendem");  
    console.log(_md5);
        //360f72d87fd979f902a69f75d11ea498

    console.log(jsutil.isMD5(_md5));
        //true

    console.log(jsutil.maskcode("This is Sample Text","*"));
        //Thi************Text

    console.log(jsutil.toTitleCase("This is Sample Text"));
        //This Is Sample Text

    console.log(jsutil.searcharray([{"id":1,"name":"alex","age":20},{"id":2,"name":"bob","age":22}],"name","bob"));
