JS String Methods

Relax. We'll talk through this in plain words — no textbook voice.

JavaScript strings are used to store text. String methods let you manipulate strings.

length: the length

slice(): cuts out a portion

toUpperCase(): converts to uppercase

includes(): checks whether text is included

javascript
let text = "Hello World!";
let length = text.length;
let part = text.slice(6, 11); // from index 6 to 10
let upper = text.toUpperCase();

console.log("Length: " + length);
console.log("Part: " + part);
console.log("Upper: " + upper);
You should see
Length: 12 Part: World Upper: HELLO WORLD!
