js string methods

// String methods:
'hello'.toUpperCase(); // "HELLO";
'LOL'.toLowerCase(); // "lol"
'    omg  '.trim(); // "omg"

// String methods with arguments:
// ==============================

//indexOf returns the index where the character is found (or -1 if not found)
'spider'.indexOf('i'); //2
'vesuvius'.indexOf('u'); //3 - only returns FIRST matching index
'cactus'.indexOf('z'); //-1 not found

// slice - returns a "slice" of a string
"pancake".slice(3); //"cake" - slice from index 3 onwards
"pancake".slice(0, 3); //"pan" - slice from index 0 up to index 3

// replace - returns a new string, with the FIRST match replaced
"pump".replace("p", "b"); //"bump" - only replaces first "p"

// String Template Literals
// Use backtick characters, NOT SINGLE QUOTES!
