The Typescript switch statement (or switch case statement) evaluates a given expression. It then matches the result of that expression with the values in the case clause. If it finds a match, then it executes the statements associated with that matching case clause. It also executes the statements in cases that follow the matching case. You can break out of a switch using the break statement or using the return statement
Typescript if statements run a block of code only if an evaluation of a given condition results in true. If statements can be used with else clause, If else if clause and as nested if to control the flow of the program execution.
Typescript operators perform some operation on one or more operands and produce a result. The operand is the data or value on which an operation is to be done. For Example, in the expression 10+2 + is an operator, while 10 & 2 are the operands.
The operator precedence along with their associativity determines how Typescript evaluates an expression when there are multiple operators present in the expression. Each Typescript operators have certain precedence. The Typescript evaluates the operators with higher precedence first. If a group of operators has the same Precedence, then it evaluates them either left to right or right to left, depending on the operator’s associativity. The table end of the article. has a list of all operators, with their precedence along with associativity.
The comma operator separates each of its operands and evaluates all of them from left to right. It returns the value of the last operand.
