<<<<<<< HEAD کاراکترهای “خاص” دیگر و غیر متداول هم هستند:https://fa.javascript.info/string#head-karaktrhay-khas-dygr-w-ghyr-mtdawl-hm-hstnd

<<<<<<< HEAD در کنار این کاراکترهای خاص، همچنین یک نشان خاص برای کدهای Unicode \u… وجود دارد که کمی بعدتر در این فصل آن را پوشش می‌دهیم.https://fa.javascript.info/string#head-dr-knar-ayn-karaktrhay-khas-hmchnyn-yk-nshan-khas-bray-kdhay-unicode-u-wjwd-dard-kh-kmy-badtr-dr-ayn-fsl-aan-ra-pwshsh-my-dhym

<<<<<<< HEAD لطفا در نظر داشته باشید که str.length یک ویژگی عددی است نه یک تابع. نیازی به اضافه کردن پرانتر بعد از آن نیست.https://fa.javascript.info/string#head-ltfa-dr-nzr-dashth-bashyd-kh-str-length-yk-wyzhgy-addy-ast-nh-yk-taba-nyazy-bh-adhafh-krdn-prantr-bad-az-aan-nyst
دسترسی داشتن به کاراکترهاhttps://fa.javascript.info/string#dstrsy-dashtn-bh-karaktrha
<<<<<<< HEAD برای دریافت یک کاراکتر در موقعیت pos، از براکت‌ها استفاده کنید یا متد str.charAt(pos) را صدا بزنید. اولین کاراکتر از موقعیت صفر شروع می‌شود:https://fa.javascript.info/string#head-bray-dryaft-yk-karaktr-dr-mwqayt-pos-az-brakt-ha-astfadh-knyd-ya-mtd-str-charat-pos-mdn-js-string-charat-ra-sda-bznyd-awlyn-karaktr-az-mwqayt-sfr-shrwa-my-shwd

str.at(pos)https://developer.mozilla.org/fa/docs/Web/JavaScript/Reference/Global_Objects/String/at
https://fa.javascript.info/string
https://fa.javascript.info/string
تنها تفاوت میان آنها این است که اگر کاراکتری پیدا نشود، [] مقدار undefined را برمی‌گرداند، و charAt یک رشته خالی را برمی‌گرداند:https://fa.javascript.info/string#tnha-tfawt-myan-aanha-ayn-ast-kh-agr-karaktry-pyda-nshwd-mqdar-undefined-ra-brmy-grdand-w-charat-yk-rshth-khaly-ra-brmy-grdand

تمام رشته‌ها با استفاده از UTF-16 کدگذاری شده‌اند. یعنی اینکه: هر کاراکتر یک کد عددی متناظر دارد. متدهای خاصی هستند که گرفتن کد از کاراکتر و برعکس را ممکن می‌سازند.https://fa.javascript.info/string#tmam-rshth-ha-ba-astfadh-az-utf-16-https-en-wikipedia-org-wiki-utf-16-kdgthary-shdh-and-yany-aynkh-hr-karaktr-yk-kd-addy-mtnazr-dard-mtdhay-khasy-hstnd-kh-grftn-kd-az-karaktr-w-braks-ra-mmkn-my-saznd
