There we have every method in JavaScript sorted by the object the method is attached to. The only thing not included there is globalThis.

JavaScript has many ways to compare data. There are both strict and pliant comparisons avaialable Strict comparisons require the type of the data as well as the values be identical. For this, a number can only match a number and they must have the same value, a string only matches another string with the same value, etc. The more pliant comparisons check for a match to the data value, and does not care about the MORE q

Conditional Statements test a claim and then either run a block of code or pass to the next step. Ultimately, these statements provide dynamic programmed responses where data can be set programmatically or change, like in the case of user input, and the JavaScript code can respond in different programmed ways. Conditional Statements: if - When a condition is met, run a block of code. else - When a condition is not met in an if statement, run a different bloc MORE q
