In this post, we’ll illuminate the most essential JavaScript string methods, breaking them down into clear, visual categories:
- String Access & Search: charAt(), charAtCode(), at(), includes(), startsWith(), endsWith(), indexOf(), lastIndexOf(), search(), match()
- Accessing & Searching Characters: slice(), substring(), substr()
- String Modification: concat(), replace(), replaceAll(), toLowerCase(), toUpperCase(), trim(), trimStart(), trimEnd(), padStart(), padEnd(), repeat()
- String Splitting & Joining: split()
Let’s dive in and visualize exactly how these methods handle your text data under the hood.
