Welcome To Code Bengali Channel we will seeindexOf and lastIndexOf. Definition and Usage The indexOf() method returns the first index (position) of a specified value. The indexOf() method returns -1 if the value is not found. The indexOf() method starts at a specified index and searches from left to right. By default the search starts at the first element and ends at the last. Negative start values counts from the last element (but still searches from right to left). Definition and Usage The lastIndexOf() method returns the last index (position) of a specified value. The lastIndexOf() method returns -1 if the value is not found. The lastIndexOf() starts at a specified index and searches from right to left. By defalt the search starts at the last element and ends at the first. Negative start values counts from the last element (but still searches from right to left). ***************** Must Watch Video ****************** ➡️ JavaScript introduction--:: https://youtu.be/kAOJe9y17_o ➡️ JavaScript Variables--:: https://youtu.be/yFRlXSFX__4 ➡️ JavaScript Function create--:: https://youtu.be/rtUz7GA4IdE ➡️ JavaScript Arrow function--:: https://youtu.be/cp9rGHgFQJQ ➡️ JavaScript Template literals --:: https://youtu.be/inVynulVD38 ➡️ Add Html Tags in JavaScript --:: https://youtu.be/2ZLcBg5_Txs ➡️ Comment In JavaScript --:: https://youtu.be/5tN1NsFn0S8 ➡️ Data Types in JavaScript --:: https://youtu.be/DL5H70fRIRo ➡️ Arithmetic Operators in JavaScript --:: https://youtu.be/PnweyNo8QUA ➡️ Assignment Operators in JavaScript --:: https://youtu.be/p9pUSysQLy8 ➡️ JavaScript Console--:: https://youtu.be/oDjVl3wuKKE ➡️ Comparison operators in JavaScript--:: https://youtu.be/N17D2cO6x8I ➡️ if else statement in JavaScript--:: https://youtu.be/_-w2dCO4M2A ➡️ Logical Operators in JavaScript--:: https://youtu.be/1YFozxPrWZ0 ➡️ Ternary Operator in JavaScript--:: https://youtu.be/WICDC4T6hno ➡️ Switch Statement in JavaScript--:: https://youtu.be/glRMNGEN6rA ➡️ else if Statement in JavaScript--:: https://youtu.be/oDQpRgqH-1I ➡️ Alert Box in JavaScript--:: https://youtu.be/LQa8rBp1t64 ➡️ Confirm Box in JavaScript--:: https://youtu.be/NeimH-a6lSc ➡️ Prompt Box in JavaScript--:: https://youtu.be/cAfc5RrfmzI ➡️ JavaScript Function Parameter--:: https://youtu.be/BYELk66a28w ➡️ Function Return in JavaScript--:: https://youtu.be/F6KIP8_zwtI ➡️ JavaScript Scope Local Global--:: https://youtu.be/HE1RHbcCNzQ ➡️ JavaScript Events --:: https://youtu.be/VSa2agFUdCM ➡️ While Loop in JavaScript --:: https://youtu.be/UDAa7TDJpmE ➡️ do While Loop in JavaScript --:: https://youtu.be/rXbe89ThlfI ➡️ For Loop in JavaScript --:: https://youtu.be/MVKYPW9QY-k ➡️ Even or Odd find in JavaScript --:: https://youtu.be/LHjnzGDIgfY ➡️ Break and Continue in JavaScript --:: https://youtu.be/VzIz27DQUbQ ➡️ JavaScript object--:: https://youtu.be/r6mlQdcgCaw ➡️ For In Loop in JavaScript--:: https://youtu.be/jO2RtnpQGQ4 ➡️ Date Objects in JavaScript--:: https://youtu.be/0bNzhTQKpsg ➡️ Destructing Arrays in JavaScript--:: https://youtu.be/ocQmQbIh7Lw ➡️ Creating an Array in JavaScript--:: https://youtu.be/WR8UW9u7FFo ➡️ Update And Delete Arrays Element--::https://youtu.be/Sk8J3B2LwmE ➡️ Sort and reverse Array method--::https://youtu.be/A2ttwvmGL6Y ➡️ push And pop Array method--::https://youtu.be/EORxDtjaWxY ➡️shift And unshift Array method--::https://youtu.be/Pqiiqhc_bXg ➡️slice And splice Array method--::https://youtu.be/6uCGKK9DG9A ➡️Objects Destructuring in JavaScript--::https://youtu.be/kzrlIjlzJP4 ➡️Swap Two Variables JS Program--::https://youtu.be/QKQmAIShA9c ➡️is Array Method in JavaScript--::https://youtu.be/ISg3T2HcZMA ➡️swap the variable's values--::https://youtu.be/mca-xrjXFyY ➡️Array forEach in JavaScript--::https://youtu.be/pug8tULgiGI ***************** React JS Tutorial ****************** ➡️ React JS Environment Setup --:: https://youtu.be/8A92a534MZU ➡️ React Folder Structure And NPM --:: https://youtu.be/Gv4t40FAhfM ➡️ React JSX and React Render --:: https://youtu.be/v-MnPDHkvO4 ➡️ Fragments in React --:: https://youtu.be/zBQfCRx2tss ➡️ Expressions in JSX --:: https://youtu.be/H2Utml_uxg4 ➡️ JSX Attribute in React --:: https://youtu.be/a929qR_YvgM ➡️ CSS in React JS--::https://youtu.be/tqIGMppDMxs ➡️ Google Fonts in React JS--::https://youtu.be/yVfnRdcQGJ4 ***************** Node JS Tutorial ****************** ➡️ Install Node JS Node.JS Script--::https://youtu.be/QNKQAkSMKcY ➡️REPL in NodeJS--::https://youtu.be/pH8aQWabYxI ➡️REPL in NodeJS Module and method--::https://youtu.be/AkfjMYXQN-s Please support my channel by SUBSCRIBE to my channel and share my videos in your Social Network.
