JavaScript Notes

JavaScript
    // substring and substr String methods
    // str.substring(from, to)
    // str.substr(from, length)
    
    let str = "Nobody calls me Lebowski you got the wrong guy I’m the Dude, man.";
    let log = console.log;
    
    log(str.substring(16, 24);	// returns “Lebowski” 
    log(str.substring(16);	// returns “Lebowski….to end of string” 
    log(str.substr(16, 0);	// returns nothing
    log(str.substr(16, 9);	// returns “Lebowski”
    log(str.substr(-16, 9);	// returns “m the Dud” (negative means start at end of string and move backwards)
